Lindsay Lohan lohandiesel1224081.jpg Lindsay Lohan's rep tells the NY Post that her recent (and pretty drastic) weight loss is due to stress and nothing else.

Her rep tells the paper, "Lindsay is aware that she's lost some weight due to stress, but we recently did a photo shoot and she ate two full meals."

But what's stressing her out? She's looking great, she's got some projects in the works, and her relationship with Sam is supposedly fine, so...what do you think is going on?
