She was a finalist on Season Four of American Idol. Jessica Sierra... one of the judges favorites... the brash, throaty singer who was part punk, part rock and just a little too dangerous for prime time. She went on to tour and record, and to party and drink. Next stop was VH1's Celebrity Rehab. Along the way, she pleaded no contest to cocaine possession, did some jail time, and made a full-on, hardcore sex tape with a boyfriend that's every bit as wild as everything else she does. Get ready. Jessica Sierra will make your pulse race and your head spin... and that's no idol threat.
