Late last year, Martha wrote that Lindsay Lohan was looking frighteningly thin, and that many of Lindsay's pals were blaming Samantha Ronson for the severe weight loss. In fact, many media outlets reported that the couple was in a sort of dieting competition, and that Lindsay was going to extreme measures to keep up with Sam's naturally thin frame.

With Lindsay looking scarily skinny again, speculation as to why is running rampant, but Lindsay told a reporter from US magazine why she's dropped a few pounds. Basically, she said, it's due to stress and lack of sleep when she travels.

She told him, "I eat. I had my Big Mac yesterday from McDonald's. I eat just as much as I always have." She then admits she that, while she's down a few pounds, she has no idea how much weight she's lost because she's never weighed herself in her life. Ummm, right. One Big Mac does not a healthy diet make -- I don't believe for a second that she's eating well or taking care of herself. Do you?
