Earlier today, via the time-honoured medium of shouty wrestlers, Big Brother gave the housemates their weekly shopping task: Nemesis. In this dramatically-named task, the housemates have all become wrestlers, sort of.

They've got wrestler names like Hotshot Hazel, Dexter the Devious, Cowboy Callum and Sophie Slamdown. They've got wrestler outfits. They've got raw eggs as a nutrition choice. And of course, because the task is all about nemeses, they've each got a nemesis.

So let's analyse the nemeses!

Hotshot Hazel vs Gina Warrior Princess
This is the only nemesis pairing that has been announced to the House so far, and it was hardly a surprise. Though these two get on quite well on the surface, Gina has made no secret of the fact that she has very little love for Hazel. Their battle is sure to get pretty sticky, so, er, stick around.

Cowboy Callum vs Dexter the Devious
Another pair of nemeses as plain as the nose on your face, these two barely go a day without a nice long chat. Unfortunately, these chats are always about how much they dislike each other. Their battle will be a battle of bravery.

Slamdown Sophie vs Sam the Strong
This rivalry is perhaps the quietest of them all, but these two haven't really seen eye to eye since the early days and, with Sam nominating Sophie this week, it seems that even their spell in the Safe House couldn't fix that rift. This battle will be one of strength and speed, and while you might think Sam's a shoo-in, never forget that Sophie is a karate master!

Jackadore vs The Jaded Joeker
That's right, the twins themselves will be facing up as nemeses. We don't even know what their battle will entail, because it's shrouded in mystery and intrigue but with theirenviable trash talking skills, we're really hoping it's a task that tests their motormouths.

As ever, make sure to check back here for task videos, and follow us on Twitter for updates throughout the day.

Let's, as they say, get ready to rumble...
