The comedy game show - which is hosted by Greg Davies and Alex Horne - will welcome the 'Four Weddings and a Funeral' star and the 32-year-old TV presenter to compete in a range of perplexing and extraordinary challenges.

They will be joined by three other famous faces, including 'Strictly Come Dancing' head judge Shirley Ballas, Channel 4 News anchor Krishnan Guru-Murthy, and 'Derry Girls' star Nicola Coughlan.

The news comes as the show reached record viewers with its latest series after it moved from Dave to Channel 4.

Series ten saw 'This Country' star Daisy May Cooper and Johnny Vegas joined by Katherine Parkinson, Mawaan Rizwan and Richard Herring.

Daisy admitted she had an "absolute blast" filming the show and is "slightly in love" with Johnny.

She wrote on Instagram: "The rumors are true, I shall be in the next series of taskmaster! It's been an absolute blast and I may be slightly in love with Johnny vegas. (sic)"

Johnny admitted Daisy is his "heroine".

He tweeted: "She scares me, but in a dangerously hilarious way #daisymaycooper you're my hero/heroine

"There is a crazy creative/anger issue fuelled crush going on between #daisymaycooper and myself. The child ain't mine but my tiny hands and task mastering incompetence are all her's. Have my points, all of 'em and take this @Channel4 @taskmaster by the f###### horns crazy lady (sic)"

However, Greg feared that Daisy - who has two children with husband Will Weston - would go into labour as she was laughing so much.

He said: “She’s a big laugher, she laughs very easily, and on many, many occasions I had to double check that we were dealing with a laugh here and not something else.”
