Life just got a whole lot uglier for Lindsay Lohan.
The trouble-prone actress began work Saturday on an extended guest spot for ABC's hit series Ugly Betty, according to Daily Variety.
Everybody's favorite mean girl is playing a former classmate of America Ferrera's Betty Suarez character, who, natch, wasn't that nice to Betty back in their school days. However, when the two bump into each other again, Lohan's character is down on her luck.
LiLo makes her debut on the show's May 22 season finale and will appear in five episodes next season.
