The 'Fresh Meat' star - who is set to host the 2018 Brit Awards in February - revealed he now insists on having contractual approval over his bottom as he is fed up of it appearing on TV.

Jack told The Sun newspaper: "Especially on 'A League of Their Own', I'm always naked. There's a lot of my a***

"I said, this series gone, 'If you show my a***, I want you to send official approval'.

"So I've been giving approval now whether they can use my bottom. It feels like you should always have approval.

"From day one, that should have been in my contract."

The 'Bad Education' star even had to expose his behind when appearing in the BBC drama adaptation of Evelyn Waugh's 'Decline and Fall'.

Jack said: "My heart sank. I thought, 'Comedy drama. Finally I might keep my clothes on.' First scene, they're down."

The 29-year-old comedian has stripped off for hit Channel 4 sitcom 'Fresh Meat', the 'Bad Education' movie and once shared a nude mudbath with Jamie Redknapp and Freddie Flintoff for Sky One quiz show 'A League of Their Own'.

Jack - who has reportedly split from girlfriend Gemma Chan after six years of dating - once revealed he was forced to show producers of 'Fresh Meat' his bottom so they could decide whether or not it was too hairy for TV.

He said previously: "I had to pull down my pants and let them look at my bottom and decide whether or not it should be waxed. They decided they didn't need to because it was a long shot. But having your bum looked at to see if it's too hairy for the screen? Amazing."
