Comedians Mark Watson and Shazia Mirza are among the ten celebrities in the next series of The Celebrity Island with Bear Grylls. They will have to endure four weeks surviving in one of the toughest environments on earth, leaving behind their friends, family, mobile phones and social media accounts.

The series has been filmed during May. At the start of the month Watson tweeted: "I am not on Twitter until June 2, because of a SECRET PROJECT. When I'm back, I hope you will have solved all the problems."

The other people in the group are Breaking Bad actor RJ Mitte, Olympian & broadcaster Iwan Thomas, actor & Rizzle Kicks singer Jordan Stephens, actor Ryan Thomas, former TOWIE star Lucy Mecklenburgh, Olympian & TV presenter Sharron Davies, former Pussycat Doll Melody Thornton and TV doctor Sara Kayat.

The line-up will also be joined by five embedded crew who will live alongside them in exactly the same conditions to help document the highs and lows of the month. Watson and Mirza are not the firsrt comedians to take part. Josie Long was in last year's series.

The Celebrity Island with Bear Grylls will air on Channel 4 in the autumn.
