Lindsay Lohan will make a guest appearance on the season finale of ABC's "Ugly Betty."

The 21-year-old actress is set to play an old schoolmate of America Ferrera's character Betty Suarez on the show's May 22 season closer, according to the trade paper Variety.

Lindsay Lohan is not exactly toasting her latest public appearance. A mugshot of the 21-year-old actress, who has been in and out of rehab after two arrests last year on drunken driving and cocaine charges, was prominently featured Friday in an advertisement attacking legislation for devices that measure a driver's blood alcohol level before their vehicle can start.

Lohan was thought to be the person who seems to be never working and always spending but alas we have found her on a location. But what the hell is Lindsay Lohan doing hanging out with the Hulk and Batman? She's found a new way to pay the bills--by filming commercials.

Earlier we reported on the best paid in Hollywood, why that list leaves the celebrities cheering, they might not be so happy to be on the '50 Dumbest People in Hollywood' list that was put together by New York Daily News.Now this isn’t that low IQ kind of dumb, it is ranked on their lifestyles and choices that they made over the last year.

Ah, Lindsay and her summer loves.They never quite make it through to Christmas, do they?Lindsay and rehaboyfriend Riley Giles are calling it quits."They're over – they've broken up," a source says. "They split after Thanksgiving weekend."Lindsay is expected to start recording her new album in the next two weeks.

Lindsay has been transformed totally into a good girl these days but before she had been so different she had been a really bad girl and committed a lot of mistakes for what she has to still pay. If you all consider the fact that she was sent to rehab because of her drugs and alcohol addiction. But the reason she was sent there was because she was accused for DUI and caught up chasing some woman with three guys in the car.
