Lindsay Lohan Shows Off Super-Skinny Figure At Ugly Betty Premiere

Lindsay Lohan stunned onlookers with her bony frame when she hit the red carpet to celebrate her appearance in the third season of Ugly Betty yesterday.

The actress looked skinnier than ever as she posed for pictures at the hit show's New York premiere party.

With her scrawny arms and miniscule waist, Lindsay looked far from healthy and appeared to be returning to her size zero form.
