JESSICA SIERRA is the latest celebrity to star in a leaked sex tape - a major porn distributor is planning to release a blue movie featuring the former American Idol contestant. The tape shows the disgraced 22-year-old in a variety of sexual poses in what looks like a motel room. The saucy footage was shot earlier this year (07) and will be released later this month (Dec07), reports website TMZ.com. The troubles are piling up for Sierra, who on Thursday (06Dec07) pleaded not guilty to charges of disorderly intoxication, resisting arrest and violating conditions of her parole on earlier felony battery and possession charges, following a drunken bar brawl in Florida last Saturday (01Dec07). Local officials claim Sierra, who is being held without bail until her next hearing on 20 December (07), begged police officers not to arrest her in return for oral sex. Sierra has had numerous legal troubles this year (07) - in November, she was sentenced to probation in relation to an April incident, in which she was accused of hitting a man on the head with a glass at a Tampa, Florida nightclub. She was also charged with cocaine possession after cops found a small amount of the illegal substance on her as she was taken to jail.
