Cameron Diaz Sweating Out the Bad Before Bikini Photoshoot in St. Barts

Much in the same manner I like to workout once a month before my hot date, or, you know, taking a girl to Arby's and telling her she can order anything off the menu, Cameron Diaz took in one last sweaty filled workout before her Vogue modeling session in St. Bart's. You certainly want to make sure your booty and body are looking just model perfect before you unleash them to the millions of Vogue readers who expect perfection.

Sure, you'll get some help after the fact from the post-production folks at the magazine, but Cameron Diaz wants to give them her best to work with. So a tight top and some shorts and some serious workout before putting on the bikinis and various other more fancy beach outfits that will encourage women to buy something from the store. This isn't Cameron's first modeling rodeo. She knows what she's doing. And we know how to watch her doing what she does. We're like a well-oiled machine. Enjoy.
