For this week's shopping task, the Big Brother 2013 housemates will be going head to head.
Each of the housemates has been given an alter ego as part of the wrestling style challenge.
They'll be paired up, but these pairings won't be friendly, with the housemates having to treat their partner like their arch Nemisis.
Throughout today the group will train for a series of head to head challenges, with help from Big Brother's pro wrestling duo Lionheart and Lion Kid.
Each of the group has been given a special name, which they must be referred to throughout the duration of the task:
Dexter the Devious
Gina Warrior Princess
Jaded Joker (Joe)
Hot Shot Hazel
Meanwhile, Charlie will act as the referee between each pairs. What she says goes, if she wants a housemate to drop and give her twenty, they do it!
As well as competing for the overall house shopping budget, the winner of in the battles between each pair will also get themselves a special £20 shopping allowance this week.
