Martin Kemp has teamed with Julian Clary, Prince Lorenzo has been partnered with The Situation, while Ashley McKenzie and MC Harvey have also become a double act for the Spandex Ballet challenge.
All three pairings must create a themed dance with traditional ballet moves.
The female housemates will act as the judging panel and score each act.
Whoever wins the task will earn a prize later this evening, which they can share with the girls.
Each routine has a title, based on a statement made by a housemate, and the duos must theme their dances around that quote.
Ashley and Harvey's title is 'I Think Things Will Be A Lot Clearer Once The Titties Are Out Of The Way' and their music is 'Finale' from Swan Lake.
Prince Lorenzo and The Situation's title is 'Lorenzo, He's Just A Bloody Sheep. Oh My God He's Totally Lost His Balls', which will be danced to 'Coppelia Waltz' by Leo Delibes.
Meanwhile, Martin and Julian will dance to 'Waltz of the Flowers' from The Nutcracker and their title is 'You Should Have Felt The Impact Of That Pie In My F**king Face And I Would Never Do That. She Nearly Knocked My Front Teeth Out'.
The task will air on Friday night's Celebrity Big Brother (August 31) on Channel 5.
