The day began with an end (get your head around that Timebomb). For her last day of luxury, Jade was awarded a pool party complete with games, cocktails and music. The housemates not already in her luxury gang had to entertain her with a talent show, with the most gifted getting a VIP pass to the party. We don’t fancy Eileen, Sally or Amy’s chances.

So they began limbering up with rehearsals. If we’re honest, it wasn’t pretty, though Danny at least looked pretty fly. Aaron loved being on the judging panel, too, unleashing his inner Simon Cowell.

It may sound like a jolly, but the task caused even more divisions in the House, with the twins and Eileen vocal about their slim chances of impressing Jade. Her response? “They’re like the Wicked Witches of the West.”

Sad news: Danny was not on the team that won entry to the pool party. He was absolutely devastated, as were the twins, who said "It must be mad to eat food." “It looks cold, though,” Eileen offered as compensation.

HIGHLIGHT OF THE DAY: Cristian played the best prank ever on Harriet (it definitely wasn’t the best prank ever). She was showering and he squeezed more shampoo onto her head every time she closed her eyes. Oh, how we laughed. And then stopped laughing. And then started laughing again because he was still doing it. There’s more Big Brother than pure drama, you know.

The mutual bathing continued and it seems that wherever women are washing, Cristian is not far behind. He and Jade got PRETTY cosy together in the bath. It was going quite well until he started doing this weird massage thing to her scalp.

We lied earlier: Cristian's prank wasn't the highlight of the day. That was Big Brother's unveiling of the nominations. The housemates' Diary Room noms were broadcast in front of everyone and it was painful to watch, though Harriet saying "hi-rate" instead of "irate" did lighten the mood. Anyway, Aaron, Cristian, Eileen, Jade, Joel and Nick are all facing the public vote this week. But there will be a twist... check back tomorrow to find out more!

Nominations have been revealed and the splits in the House are now so wide, you could drive a tractor through them.

All of this means that there should be plenty for our BOTS panelists to get their teeth into this evening.

Joining Rylan is X Factor finalist Stevi Ritchie, our good friend Matt Richardson and the one and only Aisleyne. 

But if that wasn't enough, we've also got a man who calls himself a bubble expert. 

To find out exactly what that means, you'll just have to tune in. 

Channel 5, 11pm.

The housemates awoke in 2050, which apparently looks a bit like 2015 but with naff lyrca uniforms and a fiendish edition of the Shopping Task. Under the watchful glare of Big Bot, Big Brother’s futuristic assistant, they had to prove themselves capable of surviving in a dystopian future in order to return to the past. How did they fare?

Eileen and Jade’s beef continues. Nick and Jade picked over the bones in the garden and he advised her to try and be “neutral”. Not the word we’d use for Jade. Anyway, she had a theory for the source of Eileen’s wrath: “She can’t take my mental capacity.”

Time, then, for another instalment in the  Shopping Task: Big Bot wanted to test the housemates’ capacity for telepathy. Could they guess each other’s thoughts? If you can’t intuit the answer, you’re clearly not up to scratch. 

Joel put Jade on the spot and asked if she’d sacrifice herself for Nick in an eviction. Nick piped up to say he wouldn’t sacrifice himself for her. So it’s nice to see they’re still getting on famously.

Then, more Shopping Task action. Chloe didn’t recognise the ingredient injected into her banana – and thank goodness for that – while Aaron failed to identify the taste of his mysterious cookies. But it was Eileen who made a splash, licking her lolly in a most seductive manner (well, that’s what she thought, anyway).

Eileen received ANOTHER pasting, this time from Aaron. He told Danny and Sarah that he found Eileen’s lolly-licking a bit much. Yes, this from a man who dishes out twerking lessons in the bedroom. Anyway, check back tomorrow to find out results of the Shopping Task!

We’ve got a bumper BOTS team this evening to chew over all the goss from the House.

Joining Rylan tonight are TOWIE star and ex-CBB housemate Lauren Goodger, TV presenter Matt Johnson, Shameless actress Tina Malone and comedian Matt Richardson.

We’ve also got feng shui master Priya Sher and Dr. Pam Spurr in for some expert insights.

You won’t want to miss it.

Channel 5, 11pm. 

Time waits for no man, and for our unsuspecting housemates, their time in the Big Brother House is ticking away faster than they know... Late last night, Big Brother dropped a massive bombshell on poor old Jack: the housemates who think they're up for eviction are actually safe, while the ones who think they're safe? They're facing the public vote.

Jack used one of his immunity passes to save himself, but there are now six housemates up for eviction - four of whom will be chucked out on Friday. Cruel? Maybe. But what the housemates don't know can't hurt them (yet) so let's go back to the future and find out what happened in the House today...

Housemates woke up in 2050 again this morning, as the shopping task continued. Nick, Harriet and Kieran did their bit to hold onto time by literally hanging on to time. Well, clocks. Same difference.

Speaking of time, housemates cornered Danny for a chat about whether he has a future with Sarah. He wasn't very forthcoming. Joel and Amy planned their future, too - by rehearsing their exits from the House. Joel's sounded particularly dramatic... except for the bit about dictionary definitions.

For the final part of the shopping task, Amy and Jade fixed Big Brother's time machine, sending the entire House back to 2015 - where a luxury shopping budget awaited. Hurrah!

Despite a delivery of takeaway dinner to celebrate, though, housemates still weren't completely happy. Seems someone took more than their fair share of pizza, and landed themselves squarely on Harriet's naughty list. Oh dear.

Elsewhere, Jade promised to show Big Brother a whole new Jade - which makes three of them in total, apparently. She might want to be careful with that talk of new housemates, though, because what she doesn't know is that there are some new faces waiting in the wings, ready to claim their place in the House after Friday's mega eviction. Who goes? You decide.

If we could get our hands on Big Brother's time machine right now, we'd fast-forward to Friday night to see it all go down. Unfortunately, we're just gonna have to wait.

And after so many bombshells today, who knows what tomorrow might bring?

We're less than three weeks into this series, and we've already seen some shocking twists go down. But this week's bombshell is the most explosive yet...

Because Big Brother has changed the game. This week, the most nominated housemates aren't the ones who'll face the public vote. Instead, the tables have been turned - they're safe, and everyone else is at risk. 

So far, Jack's the only housemate who knows what's going on. Big Brother brought him in on the secret in case he wanted to use one of his immunity passes to save himself or someone else. And it turns out he did - he saved himself, putting Chloe, Danny, Kieran, Sarah, Harriet, and the twins up for eviction, before being sworn to secrecy.

And there's more. In the biggest eviction in Big Brother history, not one, not two, not three, but FOUR housemates will be shown the door on Friday night.

That's right, it's a quadruple eviction. It's going to be emotional. It's going to be dramatic. It's going to completely change the entire House dynamic. We can't quite believe it's actually happening, but trust us - it really is.

The lines are open now, and the housemates' fate is firmly in your hands.

 Time to get voting!

(If you were watching Bit On The Side, you might have spotted that there's something else going down on Friday, too. But we'll just have to wait to find out more about that...)

We just can't think what Rylan's going to have to talk about this evening. Oh, that's right. One of the biggest, most shocking twists in BB history.

Joining him to give their views on all of it we've got former CBB star Kellie Maloney (she won't be pulling any punches), TV journalist Edward Gleave and ice skating star Matt Evers.

This is one episode you simply can't afford to miss.

Channel 5, 11pm.

Friday will see Big Brother drop the most explosive Timebomb yet - and in another Big Brother first, it's set to be a quadruple eviction. Can't wait? Neither can we. Make sure you tune in to the two hour Big Brother: 4 In, 4 Out at 9pm, and then stay put for Big Brother's Bit On The Side at 11pm until midnight. 

In the meantime, here are all the facts ahead of what will be a highly dramatic live show:

• Nominations have been flipped on their head

The housemates who received the highest number of nominations think they're facing the vote. But for once, they're not. Big Brother has flipped the script, so that the housemates with the fewest nominations are the ones up for eviction.

That means while Jade, Nick, Cristian, Eileen and Joel are safe, Danny, Kieran, Chloe, Harriet, Sarah, and the twins all face the chop. 

• Only Jack knows about it

Thanks to the launch night timebomb, Jack had the option to claim immunity from eviction for himself or one of his fellow housemates. So Big Brother called him into the Diary Room and spilled the beans.

Jack saved himself, and Big Brother swore him to secrecy. Even hinting that nominations might be something other than they seemed to another housemate would see Jack immediately shown the door. Gulp.

• Four unsuspecting housemates are getting the boot

Jack doesn't know everything, though. Because this is no ordinary eviction. It's not just one oblivious housemate who'll get the boot - it's four. Yes, four. Four. Let that sink in for a moment. It's a quadruple eviction. Utter carnage.

• And four new ones are going in - including one you'll recognise

To stop the House feeling quite so empty, Big Brother is going to chuck in a few new faces. We'll meet the newbies tomorrow night, but they sound extremely interesting... and you might just recognise one of them. To give you a little sneaky teaser of what to expect on the whole though (shhhhh), there's a 29-year-old final year science student who's also a ‘UK Pleasure boy’, a 22-year-old model who's worked as a dominatrix, and a part Sri Lankan singer and entertainer whose attitude is ‘flirt with the world and get stuff for free’.

• It'll all kick off at 9pm tomorrow 

Put it in your diary, clear your schedule, and set an alarm. You absolutely cannot afford to be anywhere other than sitting in front of your telly at 9pm tomorrow night.

• And Emma Willis is loving it

What does the reigning queen of Big Brother make of all this drama? Predictably, she's LOVING IT. "Just when they were adjusting to life in the House, Big Brother is about to drop a whopper of a timebomb," she said. "I can't wait to see how the surprise mass eviction, some brand new housemates, and a very familiar face go down."

Neither can we, Emma. Neither can we.

Well, today didn't get off to the best start. This morning, Big Brother announced to the housemates that Aaron had been removed from the House, following inappropriate behaviour last night.

Tomorrow night's eviction was the cause of tension, too. Housemates couldn't seem to stop themselves from wondering and speculating about what might happen. Which has led to some tricky conversations for Jack, as Big Brother has confided in him that there's a nominations twist coming up...

He's been doing his best to keep schtum though. Well done, Jack. Not much longer to go now...

To pass the time between now and then, though, housemates decided to give Joel a makeover. In Eileen's clothes. Well, sure, why not? 

The girls also spent some time discussing Cristian. They've given him a new not-entirely-affectionate nickname: "cringebag." Oh dear.

Tomorrow night is going to see a massive, massive change in the House, when we chuck four housemates out and put four new housemates in. There's still time to vote on who gets evicted, but the clock is ticking...

Today's one of those days that's going to go down in Big Brother history. We chucked four housemates out - and put four new ones in, all on the same night! Plus the housemates who were evicted didn't even know they were facing the vote. Drama all round. Let's take a moment to soak it all in, every moment of it...

Cristian didn't have the best start to the day, clashing with Kieran over what should go in the fridge vs the cupboard, and then rowing with Harriet over the

washing up. Seems the stress of eviction day was getting to him.

He wasn't the only one with the eviction on his mind, either. Sarah gave Joel some sage advice about how to face the night, while Jack struggled to keep it together as housemates speculated wildly about what might be going on. Some of them even came worryingly close to the truth... but not close enough!

As day turned into night, eviction time rolled around. And while an eviction is always an emotional time in the night, this one was extra special. Big Brother finally let the housemates in on the secret Jack's known all week - that the housemates facing the public vote weren't the ones who'd been nominated. Judging by their faces, we think they were pretty shocked.

And it didn't stop there. Amy and Sally were the first ones out of the door, but they weren't the last - far from it. As the housemates strugged to get used to the idea of losing the twins, Big Brother unveiled something special in the garden - the Timebomb Machine. Three housemates entered, but only one came back out, as both Harriet and Kieran were sent out to meet Emma. 

The Timebomb Machine had another trick up its sleeve too - it introduced two new housemates, Harry Amelia and Marc - into the fray. Exciting!

Even that wasn't the end of it, though. New housemate Sam sneaked into the Diary Room, and before she was allowed into the House for real, was made to announce the name of the evening's final evictee - Sarah. 

The cherry on the top of it all was the re-introduction of one more new housemate: Simon! Turns out he hadn't taken his final bow after all, and Mr Showbiz has reclaimed his place in the Big Brother House. For now, anyway. And the new housemates are already causing ructions, with Jack and Joel wondering how they're going to fit in.

Looks like the House is going to be a very different place from tomorrow. We can't wait to see what happens.
