Since Keira Knightley became a mom in 2015, she’s had a no-nudity clause in her contact. “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,” the Oscar-nominated actress told The Farewell director Lulu Wang and writer-producer Diane Solway on the Chanel Connects podcast. Knightley recognizes that there are times when “sex would be really good in this film and you basically just need somebody to look hot,” but that’s what body doubles are for.
