Lindsay Lohan Defends Weight: I Just Ate A Big Mac (PHOTOS)

Lindsay Lohan, asked by US Weekly at Fashion week about her weight loss, insisted all was ok and "it's not intentional."

"I eat. I had my Big Mac yesterday from McDonald's," she told Us Sunday at the Matthew Williamson NYC store opening. "I eat just as much as I always have."

The 22-year-old actress (who has raised eyebrows before for her skinny frame) said she thinks she has just been "working a lot." She said she also blames "stress ... and lack of sleep when I travel."

Other papers have jumped on her skinnier frame, which comes right as she and girlfriend Sam Ronson are having public spats.
