Cameron Diaz has sparked speculation of a breast enlargement after her latest outing in a tiny bikini. The Charlie's Angels star, 39, was spotted on the beach in Hawaii over the holidays looking rather shapely, prompting rumours she's gone under the knife. Cameron Diaz almost flashes her boob and suffers apparent nip slip on set of new movie. The star's dress slipped to the side to reveal a little more than she hoped and she flashed her knickers as she sat down. The red band trailer for Cameron Diaz and Jason Segel's latest vehicle, a movie about profound love and the meaning of human relationships in an age of technology, was released yesterday. It's called Sex Tape. There are boobs.
