Cameron Diaz took her water to go in a glass bottle after a workout in LA today. She's at her West Coast home base after a busy month of jet-setting that's included stops in NYC and London. Cameron's been on the go chatting up her movie What to Expect When You're Expecting with a rotating cast of her many costars, including Jennifer Lopez, Brooklyn Decker, Chace Crawford, and Chris Rock. Their last big press stop was last week in London, where Cameron's BFF Gwyneth Paltrow has been hanging out with her kids, Apple and Moses. What to Expect came out on May 18 to mixed reviews, and the ensemble picture ended up getting beaten at the box office by a string of early Summer blockbusters, like The Avengers and Men in Black 3.
