Keira Knightley was forced to smoke cigarettes and talk about sex with her mother when she was growing up. She admits her mom is "a bit mental" and says her childhood was unusual.
"My mother and I would always talk about sex. She’d come up to my room and have me roll cigarettes for her and then tell me I had to have one with her."
"Not the typical mother-daughter thing. But we’re extremely close. My mother’s a bit mental – in a good way. She’s a chilled-out hippie."
Keira, who flashes her right breast in Britain’s Esquire magazine, insists she’s fine with going topless – she will never show her butt on camera.
She said: "I don’t mind about the boobs, not the butt… I’m a woman. There’s no reason to it."
