The trio will all feature as themselves in 'The Celebrity Circle for Stand Up To Cancer', which will air on March 9th on Channel 4, and the likes of Baga Chipz, Kaye Adams, Nadia Sawalha, Sam Thompson, Pete Wicks and Charlotte Crosby will appear under a celebrity catfish profile.
Kaye and Nadia will play the game as TV star Gemma Collins, and Sam and Pete will be playing as 'Countdown' co-host Rachel Riley.
Charlotte, 30, will join the game as pop star Peter Andre, and Baga will play as Kim Woodburn in the celebrity series, which will see the well-known faces move into The Circle's iconic apartment block, where they can only communicate with each other through a virtual platform called The Circle.
Emma Willis will return as the show's host, and comedian Sophie Willan is also reprising her role as the narrator.
The series - which will also see Rickie Haywood-Williams and Melvin Odoom play as will.i.am - was filmed in autumn last year, and the celebrities had no idea who was catfishing and who was playing as themselves.
The star-studded show is in aid of Stand Up To Cancer, a joint national fundraising campaign from Cancer Research UK and Channel 4 that brings the UK together to speed up progress in life-saving research.
What's more, the six-part celebrity version will be quickly followed by the new third series of 'The Circle'.
Emma, 44, previously admitted to being sceptical about 'The Circle' before she understood the show's concept.
She explained: "Before I'd watched it, I was like, 'This is glorifying what is wrong with social media, where anyone can be anyone. You don't know who you're talking to.' "But I hadn't watched it and that was just my opinion.
"Then I watched it and I thought 'This is a glowing beacon to teach people, do not trust who you're talking to online. Because you just don't know!'
"So I think it's a brilliant vehicle for education in the way that a game is showing you that you should be so wary of anything that you're doing online, who you're talking to."
