Halle Berry wore a bikini top yesterday to hit the beach in Malibu with friends. Her fiancé Olivier Martinez wasn't among the group, but he and Halle were side by side Saturday for a LA lunch date. Halle's back on the West Coast after recently traveling to Toronto to debut her film Cloud Atlas. The picture, which costars Tom Hanks, is an ambitious big-screen adaptation of a book from author David Mitchell. Early reviews of Cloud Atlas were mixed, and fans will be able to see the finished product themselves when the picture arrives in movie theaters on Oct. 26.
