The actress, who has done nude shots in films like the Devil"s Advocate and Monster, insists that she strips only if the script truly demands it.
She told USA Today newspaper: "I'm not some exhibitionist. I think people think I just love walking around naked. When you start making it about yourself, you stand in the way of doing your job. I have to sit in an editing room with the director and a bunch of execs, and if I had to sit there and think about myself and these men watching me, I think that would make me insecure. I'm just like every other girl out there. I would cringe."
The Monster star confessed that the new film in which she plays Sylvia, a woman who found out her mother was having an affair when she was a teenager, reminded her of her own adolescence. In real life, Charlize"s father was shot dead by her mother after he attacked her when she was 15, the China Daily reports.
She added: "I looked at my parents and I was so judgmental, and you don't understand the struggles of what it is to be in a marriage and be committed and raise children and to be part of a family. Their marriage wasn't great. As a child, you see things very differently, and then I got older and I went, 'Wow, that's amazing.' You start going out with a couple of boys, and some of them aren't so nice. There's a lot more that plays into this whole relationship thing than you think."
