Keira Knightley refuses to strip off for nude scenes now she's a mum of two over fears her "nipples droop".
The actress, 34, has two daughters with her musician husband James Righton and admits that although she still loves her body, she doesn't want to stand naked in front of a film crew any more.
In an interview with The Financial Times , the actres joked: "The nipples droop!"
She went on to explain: "I always felt completely comfortable doing it when I was younger. I never did anything that I didn’t feel comfortable doing.
"I'm really happy with my body. It's done an amazing thing. But I also don't want to stand there in front of a whole film crew....
"That was a choice [not doing any more nude scenes]. I get to choose the body double
"It is an interesting selection process! It kind of goes like, 'That's a little bit like you, but better.
"She has a lovely body, so she can do this'... then I get final approval of what the edit is.''
Keira added that although she has stripped topless in several movies, including The Duchess, she never felt like any of her saucy scenes "went too far".
The actress went on to add that she also fears that nowadays some racy scenes could end up being added to porn sites.
She said: "It used to be that you’d do a sex scene in isolation with the film, and it would make sense.
"And maybe a... paper would put it somewhere but, ultimately, that would be it.
"But now, you can take the whole thing and put it in a completely different thing, and it’s on some porn site."
Keira and James married in 2013 and they are parents to two daughters, Edie, four, and Delilah, who was born last year.
