Actor, David Tennant has revealed that his most embarrassing on screen moment was when he had to fake an orgasm. On last nights chat show, Parkinson, Tennant revealed:

“Pretending to climax on screen is about the most embarrassing thing I have ever done.

“It was in a film once quite a long time ago. It’s only because it’s a relatively private experience, let’s be honest.

“There are all these cameras and everyone else watching you and you go for it as best as you can.

“There’s a sense that when they say ‘Cut’, you think ‘Is that what everyone else does?’.

“It’s not pretending to have sex that is embarrassing. Hopefully you’re with an actress and you’re in the same boat and you are just getting on with it.”
