Cameron Michelle Diaz (born august 30, 1972) is an american actress and former fashion model. She is perhaps best known for her roles in popular blockbuster movies such as The Mask, There's Something About Mary, My Best Friend's Wedding, Charlie's Angels, Shrek, and Gangs Of New York. Cameron Diaz suffers from obsessive-compulsive disorder, and has publicly admitted she habitually rubs doorknobs so hard before opening doors to clean them that the original paint on the doorknobs fades afterwards. She says, she washes her hands many times each day and uses her elbows to push open doors. Diaz has perhaps modified her fears somewhat, saying on may 10, 2007, Ithink I've made my peace with it.
