OK, this is one of the most bizarre celeb stories we've ever heard. But it's so amazing, we had to pass it on:

An ex-barista from a New York Starbucks claims that he's been altering Mary-Kate and Ashley Olsen's morning coffee drinks because he was concerned about their skinniness. While the twins ordered fat-free beverages, "the barista thought the Olsens were too thin, so whenever they ordered their usual drink, he would replace the skim milk with full-fat," OK! magazine reports. MK and Ash's rep denies the story, calling the claim "ridiculous." Yeah, ridiculously hilarious!
