While former "American Idol" finalist Jessica Sierra completes her current sting in rehab in nearby Pasadena, Vivid Entertainment, leading adult film studio, is set to release a steamy sex tape starring the troubled singer.

Sierra, who was the third finalist eliminated on the fourth season of "American Idol," will be starring in the forthcoming DVD called "Jessica Sierra Superstar."

"It's an exceptionally explicit series of vignettes, both solo and with Charles 'C' Youngblood, a man she met at a Hooters bar in Tampa. The tape also reveals much about the personality of Jessica and gives some insight that would be helpful for anyone curious as to how she has arrived at her current situation in life," said Steven Hirsch, co-chairman of Vivid Entertainment.

The tape is comprised of scenes captured in various locations around Tampa, said Vivid, including a hotel room, driving in her car and other places.

Sierra has led a stormy life, since failing to become America's next "Idol," which has included run-ins with law enforcement and drug problems.

She is currently one of the bold-face names documented in VH1's new reality series, "Celebrity Rehab with Dr. Drew," in which David Drew "Dr. Drew" Pinsky follows the detoxification and treatment process of show business personalities.

Right now, however, she currently resides at the Pasadena Recovery Center, which she entered after a Florida judge granted her a special 45-day travel permit. He had sentenced her to serve a year at an in-house drug treatment facility followed by three years of probation after a trial for disorderly intoxication, resisting arrest without violence and other charges stemming from an arrest for an incident that occurred outside a bar in Tampa last month.

In sentencing Sierra, Hillsborough County Circuit Court Judge Daniel Perry also forbid her from using treatment as a way to aid her celebrity status and thus "glamorize" being a drug addict. The judge ordered her to stay at least 100 yards away from microphones and cameras.

Vivid says they obtained the sex tape prior to the sentencing.

"Jessica Sierra Superstar" will be released on DVD and online on January 30. For more information, visit JessicaSuperStar.com.
