Poor Cameron Diaz.

The fun-loving actress isn't trying to pull a Britney Spears or Paris Hilton in this photo. Wind just happens sometimes.

While on the set of her new movie with Ashton Kutcher, Diaz accidentally gives the world a look at her rear end, which is considerably smaller than that of Kim Kardashian. Then again, so is Neptune.

Bradley Cooper is a lucky man. He's rumored to be dating Cameron Diaz and can look at this whenever he wants to.
