John Barrowman leaves reality TV show Celebrity SAS after 32 minutes

He said: “The press accused me of going around everywhere and blaming everyone for my actions.

“Having this happen to me has ruined me, but this course will help me get through it and I want people to see what kind of person I really am.”

He later added: “On Doctor Who and Torchwood I had to do a lot of nude scenes. If I were stupid, I would do something stupid.”

“I would shake and wiggle or do a scene with one of my testicles hanging out.

“The press has painted me as a sexual pervert. We’ve all done stupid and silly things, but what is being said about me will never go away.”

Contestants in this series include Rachel Johnson, sister of former Prime Minister Boris Johnson, reality star Pete Wicks, former Olympic gymnast Ellie Downie, comedian Tez Ilyas, professional basketball player and Love Island star Ovie Soko and world heavyweight boxing champion Lani Daniels.
