UGLY LINDSAY: Lindsay Lohan Stars on 'Ugly Betty'

Lindsay Lohan will appear in the season finale of ABC's “Ugly Betty.”

Lindsay will play Betty's high school friend in a flashback scene. She takes the role of an old schoolmate of America Ferrera's character Betty Suarez. The 21-year old actress already started her shooting during the weekend. As a matter of fact, LiLo (as dubbed by her fans) was praised for coming to the set early.

Lindsay's appearance on the sitcom will be aired on the show's May 22 season closer. LiLo is also expected to appear in five episodes of "Ugly Betty" next season.

Like her friend Britney Spears, LiLo has been through rough times with her bad media publicity last year.

Like Britney Spears, she has also been disturbed and still struggling with her continuing downward spiral career.

And like Britney Spears, she will make a cameo role in top rating television show too, hoping to make a good impression for the press and the public.
