Although Blake Lively is only 24 years old, she's already set in her ways when it comes to movie nudity: no skin on screen, ever!

'When I see nudity in movies, I am always distracted by it," she tells the UK's Daily Mail. "I know that if I am watching a scene and someone has their boobs out, then that's all I'm looking at - I can't help it. I just don't think that will ever be right for me."

We think that, like we said, Blake is only 24 years old, so she's got plenty of time to change her mind on the issue. And we're hoping she will.

To clarify: by "on screen," Blake means movie screens-- cell phones are another matter entirely. See the evidence with leaked nude pics of Blake Lively right here at the Mr. Skin blog!
