Cameron Diaz has been in the biz since her breakthrough role in The Mask alongside Jim Carrey in 1994, and since then she says she’s always done what she wants to do, when she wants to do it. She’s always been true to herself, and is keeping it that way. Cameron Diaz (Bauer Griffin)

She said: “I don’t feel like I need to prove anything to anybody. When you start out and people identify with you they want to keep you how they remembered you the first time they fell in love with you. It’s like a relationship. But that doesn’t concern me as I’ve always tried to be true to myself and move at a pace that was right for me.” Since her breakthrough role, Cameron has starred in a wide variety of films, including The Holiday, Shrek and My Sister’s Keeper, in which the actress played a mother who had to watch her daughter battle cancer. The 37-year-old blonde admits her role in My Sister’s Keeper was one of her most challenging, but the director Nick Cassavetes was a great help on set. She added to Sky Magazine.
