Mischa Barton is Obsessed with Pilates

Mischa Barton is one of those trendy celebs who the tabloids love to watch for any sort of weight gain or loss, with the most recent judgement being that she is absolutely too thin to be healthy. But despite being scary skinny, the star is quick to admit that it's not because she's living on a diet of drugs and alcohol, it's because she's obsessed with exercise -- pilates in particular. "For me, it's all about Pilates recently. I'm obsessed with Pilates. I think it's so fun," she recently admitted.

OK, fair enough. Pilates is a great workout -- but from my experiences, it should lead to toned, not bony. Nonetheless, she doesn't want us to worry about her. "I don't do any crash diets," she told "OK" USA, adding "I do more cardio because I work long hours. Jogging, running - stuff like that's really good before you do a film so you have more energy."
