Cameron Diaz kept the good times rolling this year. She split from boyfriend Alex Rodriguez, but bounced back with the help of her girlfriends like Gwyneth Paltrow and Stella McCartney. Cameron was even a bridesmaid at her pal Drew Barrymore's wedding.
She shot Gambit in the late Summer, and later switched gears to promote What to Expect When You're Expecting before its May 2012 release. Cameron was in the headlines throughout the year thanks to her rumored romance with Diddy, and later, when she chopped off her trademark long blond locks.
