TV presenter Denise van Outen and Drag Race star Baga Chipz have reportedly signed up for the celebrity edition of The Circle.
Due to coronavirus, the series is currently being pre-recorded for transmission early next year on Channel 4 in aid of Stand Up To Cancer.
With filming now underway and the contestants all in isolation, The Sun has published the names of some of the famous faces taking part.
Others joining Van Outen and Baga include loose woman Nadia Sawalha, YouTuber Saffron Barker and Charlotte Crosby of Geordie Shore.
"The creators wanted to really mix things up for the first celeb-only version, and they really feel they've achieved that with these signings," a source told the newspaper.
"It just goes to prove how the show has grown in popularity, particularly among younger viewers."
A new series of the regular civilian version of The Circle is also being filmed in advance.
