Lindsay Lohan: On Set of Ugly Betty

Looks like Lindsay Lohan is fully embracing her guest starring stint on Ugly Betty.

In this photo from the set, the Firecrotch Queen dons a long, orange T-shirt that we can't imagine she'd ever wear to Hyde.

Lohan is set to appear in five episode of the hit series, portraying a mean, former high school friend of Betty's. Word also has it that Lindsay's character will work in the fast food industry. It shouldn't be a major stretch for the actress.

She's used to doing guys things quickly.
