icky Wilson, Alan Carr, Jamie Laing and Martin Kemp are among the stars taking part in a "Great British Bake Off" celebrity special.
Each episode of the "Great Stand Up to Cancer Bake Off" will see four celebrities go head-to-head in the signature, technical, and showstopper challenges in a bid to be crowned Star Baker, and Channel 4 have now released the full list of who will be taking part in the culinary contest.
Presenters Stacey Solomon, Melanie Sykes, and Nick Hewer will all be donning their aprons, as will Diversity's Perri Kiely, journalist Bill Turnbull, Paralympic gold medallist Kadeena Cox, actor Griff Rhys Jones, singer Ella Eyre, actress Teri Hatcher and politician Ruth Davidson.
And a host of comedians will be bringing laughs to the show, with Tim Minchin, Harry Hill, Roisin Conaty, Lee Mack, Joe Lycett and Aisling Bea all planning to enter the famous tent.
Former "Desperate Housewives" star Teri's involvement was first rumoured last month.
A source previously said: "Teri is a bit of a left field choice, but Channel 4 are banking on her adding some real Hollywood glamour to "Bake Off".
"As well as being a Golden Globe-winning actress, Teri is a keen baker and the fact she jetted all this way proves she's serious about the competition.
"It'll be interesting to see what she makes of hosts Sandi Toksvig and Noel Fielding, or if she recognises any of her opponents."
The upcoming spin-off shows will be the first celebrity series of the popular programme to be aired on Channel 4, after the broadcaster won the rights to the show from the BBC in 2016.
Channel 4 aired its first main series of the show last year, where 33-year-old former Army officer Sophie Faldo was crowned victorious, after wowing judges Paul Hollywood and Prue Leith with a seven-layered, honey bee-themed entremet showstopper.
"The Great Stand Up to Cancer Bake Off" will air on Channel 4 later this year.
