The preview website shows “teaser” snippets from the video that catch Sierra driving her car while talking about sex, flashing her breast, in the bathtub, taking a shower, having sex with an unidentified person and starting to comment on other Season Four contestants.

The 22-year-old Sierra was a finalist in the fourth season of AMERICAN IDOL® but was eliminated on March 30, 2005 after she sang “On the Side of Angels.” Idol host Simon Cowell said she was one of the strongest vocalists in the competition. She originally started singing in church at the age of three and as a teenager she performed in recitals for both presidents Bill Clinton and George W. Bush.

“This title contains the most explicit sex we’ve ever seen in a celebrity video,” said Steven Hirsch, co-chairman of Vivid. “Jessica clearly has more talent than just singing.”

Vivid obtained the Sierra video from an unidentified third party. It contains 72 minutes of footage showing her having hardcore sex with a man believed to be her boyfriend at the time.

It is the latest in a series of videos featuring the sexual exploits of celebrities to be released by Vivid, including the most recent, “Kim Kardashian Superstar,” which the Hollywood socialite made three years ago with her then boyfriend, R&B artist Ray J. Others include videos made by Pamela Anderson and Tommy Lee, Vince Neil, Tom Sizemore, rock groupie Karrine Steffans aka “Superhead,” and Jennifer “Toastee“ Toof, competitor from VH1 reality TV shows “Flavor of Love“ and “Charm School.”

Sierra has been in the news recently following a series of incidents, including an arrest on December 1^st in Tampa, Florida on charges of disorderly intoxication, violation of probation and obstruction of justice. She is said to face up to 11 years in jail for the arrest, having been on probation for earlier charges of felony battery and cocaine possession. She has pleaded not guilty to the new charges. A hearing is scheduled for Thursday, Dec. 20. Previously she was arrested on April 29, 2007 in a Tampa bar, accused of throwing a cocktail glass at another patron’s head.
