American Idol Alum to Appear on Celebrity Rehab with Dr. Drew

at . Comments
Former American Idol finalist Jessica Sierra has discovered a new way to stretch out her 15 minutes of fame.

The troubled singer, who has been in a drug-treatment program in California after pleading no contest to cocaine possession, will be the subject of an episode of VH1's upcoming reality series Celebrity Rehab with Dr. Drew, premiering January 10.

Sierra is one of nine participants on the show, which will be hosted by Loveline's Dr. Drew Pinsky; others include Andy Dick, Tom Sizemore and former WWE star Chyna.

The Idol alum was arrested April 29 at a Tampa nightclub after hitting a fellow bar patron, Wisam Hadad,  in the head with a glass. Hadad said he had never met the singer; she claimed he spat at her, but later acknowledged she may have been mistaken.

She was sentenced Monday to 12 months' probation and random drug screening after pleading no contest to charges of drug possession and assault stemming from a barroom scuffle back in April.
