While she's shot a few in the past -- and admitted to employing a "bum double" for others -- Keira Knightley says she's done with on-screen nude scenes, particularly if the director is a man.
"I don't have an absolute ban, but I kind of do with men," the two-time Oscar-nominated actress, 35, told the "CHANEL Connects" podcast.
During the conversation with filmmaker Lulu Wang and writer Diane Solway, Knightley explained, "It's partly vanity and also it's the male gaze. I feel very uncomfortable now trying to portray the male gaze."
"Saying that, there's times where I go, 'Yeah, I completely see where this sex would be really good in this film,' and you basically just need somebody to look hot," she added.
The "Pride and Prejudice" star hasn't totally shut the door on onscreen nudity, but she does have one caveat. "If I was making a story that was about that journey of motherhood and body acceptance, I feel like, I'm sorry, but that would have to be with a female filmmaker," the mother of two explained.

I’m not interested in doing that," Knightley -- who shares daughters Edie, 5, and Delilah, 1, with husband James Righton -- continued.
The "Atonement" actress said directors who envision her for a role featuring nudity should look elsewhere, saying, "So, therefore, you can use somebody else, because I'm too vain and the body has had two children now, and I'd just rather not stand in front of a group of men naked."
