As the tension surrounding nominations grew, housemates from The Insiders got to work on the boy band.

The self-appointed Simon Cowell of the Big Brother House Shievonne, gathered her ‘people’ in the living room.

We got a glimpse of Ashleigh’s expectations post-BB when she demanded £60k a year to be the band’s promoter. She agreed to do it for £10k after Sheivonne negotiated her down.

The boy band is now firmly established – Conor, Arron and Luke S with vocal coach Caroline and make-up artist and personal trainer Becky.

Here’s a sneak peek of some of the lyrics including Arron’s solo, “I’m pretty boy of the pack, I like to rap until the DJ brings the beat back,” and Conor’s, “I’m Conor, I’m the beat box brute. I remind you of a passion fruit.”

The Insiders spent time mocking the outsiders who Caroline claimed looked miserable.

The band meeting fell apart when talk turned to another musical legend, Lydia’s fiancé. Housemates speculated on his identity once again. They know he is called Andy and Conor suggested it may be Andi Peters. Seems unlikely but Becky who has aspirations of being a children’s television presenter is now mortified – she has been mocking Lydia’s celebrity relationship.

The divide between the housemates is deepening and with the band taking shape, is there a chance they will make it big on the outside?  If so, they will surely be hanging in the same circles as Lydia and her fiancé...

Nominations have been announced and the names in the frame are Deana and Lydia.

Deana was first to react, directing her distain at Conor, saying, “I knew it. It’s no surprise. You got what you wanted.”

Lydia was uncharacteristically quiet and even accepted a hug from Shievonne.  Her silence didn’t last.

Speaking to Luke A she said, “I thought people would go with their own opinions but the sheep follow the shepherds. I’ve not done anything to anyone.”

She is has been fixated on a comment Deana made during Benedict’s eviction when she said she heard Lydia being booed.

But Lydia isn’t letting it knock her confidence. She added: “The winner last year got booed when he left. It doesn’t mean anything.”

After her initial outburst Deana’s solution was to get everyone involved in an egg and spoon race. Housemates were briefly united with Lydia taking the lead in her favourite type of fun – the organised kind.

Do you think housemates are following Conor’s lead or were Lydia and Deana’s cards already marked.

A clear divide has emerged in the House. On the one side, we have Shievonne, Ashleigh, Luke S, Caroline, Scott, Becky, Sara, Arron and Conor, who for now we shall call 'The Insiders'. On the other side, we have Luke A, Adam, Lydia, and Deana, which we will call 'The Outsiders'. Although Lauren has spent most of the day with 'The Outsiders', she tends to float between the two.

For most part of the afternoon and early evening, 'The Outsiders' have been venting their grievances about the others, saying the House has turned in to a playground. The tension has gotten so bad, that they're even choosing to sit in different rooms.

Although the 'The Outsiders' were annoyed with the other group as a whole, there were some specific issues that arose. Amongst other things, Lydia was annoyed that Arron had called her a "f*****g weirdo", Deana was upset at being blanked when she tried to make an effort with the other group,  and Adam and Luke A accused Caroline of game-playing.

'The Insiders' seem to have similar feelings, as they sat in the living room mocking 'The Outsiders', who unbeknown to them were mocking them too. And there ends the circle of bitchiness.

But why the sudden divide? Maybe it's the pressure of nominations? Or maybe it was coming all along...

Either way, we're calling for the Hoff to come and break the invisible wall.

Caroline has been lending a sympathetic ear to Lydia this evening, as she tried to work out why she's facing the public vote for the second time.

"You come across as a serious person," Caroline offered. "Bring out the amazing character traits you have and exterminate the seriousness."

Lydia has been smarting ever since Arron called her a "f*****g weirdo" earlier this afternoon, saying to Caroline, "I don't understand, I'm the most normal person in here."

Caroline agreed, suggesting her self-assured attitude may come across as arrogant. "If you're successful and you're a girl, it comes across like that," Lydia mused.

She then put her humbleness in to context by saying, "I could have come in here saying I had a famous boyfriend." Umm, we think you might have mentioned that already...

Caroline wrapped up the conversation, by telling Lydia she could come to her any time. However, how genuine is this offer?

Earlier, Deana told some of the housemates that Caroline is always nice to her on nomination day. Are we starting to unravel a game plan, or is Caroline just unwittingly trying to help people in the House?

Day 21 saw group tensions finally explode in two separate tribes. Allow Big Brother to introduce 'The Insiders' (Shievonne, Ashleigh, Luke S, Caroline, Scott, Becky, Sara, Arron and Conor) and 'The Outsiders' (Luke A, Adam, Lydia, and Deana). We've had the 'The Capulets' and 'The Montagues', 'The Jets' and 'The Sharks', these guys are the natural descendants.

Earlier yesterday, 'The Insiders' talked among themselves about the rift. As Day 21 merged into Day 22, three of the four 'Outsiders' showed they too knew their place. Where's that? outside of course. To avoid any confusion, the location of their chat was in the garden. Thanks for realising the importance of visual signposting, housemates.

Having established their geographical and social position, Adam, Lydia and Luke A got sound-bite-happy.

"The game's begun. It's two teams," said Luke A, still scarred by an earlier case of napus interruptus.

"It's two houses within a house," said Lydia, veering close to Shakespearean lyricism.

She then showed some conspiracy theorist stripes. "The psychologists knew exactly what was going to happen. It's all been predicted... bar a few people who they didn't know exactly what side they were going to go on." This is perhaps a reference to Lauren who, having dodged eviction, is now floating like a particularly aerodynamic bubble.

But back to Lydia's theory... What do you think? Is the gang rivalry the product of the great puppet-master, Big Brother? Or is this all just chance and pack mentality?

Hmmm, nature vs nurture... This one's deep, yo.

This week's mysteriously-named Shopping Task, '100', requires housemates to score 100 points.

Over the next two days, Big Brother will set a number of challenges giving housemates chances to win points toward their total score. Housemates may also lose points by giving in to temptation. Big Brother loves testing housemates' discipline and concentration (*cue villainous laugh*).

This morning the housemates woke up to find an empty container in the living area. Each time they win a point, a red ball will drop into the container. Each time a point is lost, a ball will drop out of the container. The balls will be counted at the end of the Shopping Task.

If the housemates manage to get 100 points or more, they will pass this week’s Shopping Task and win a premium shopping budget. But if they have less than 100 points, they will fail this week’s Shopping Task and receive an economy shopping delivery.

Food affects the mood of the housemates; will they be living off chickpeas again next week? Check back soon to see how they fare.
