Jessica Sierra -- the troubled former "American Idol" finalist who is currently in jail without bond -- is pregnant, according to TMZ.com.

Sources reportedly told the site that Sierra is in the infirmary at Falkenburg Road Jail in Tampa, Florida, and that she is on a pregnancy diet. The father is a rap artist, sources told TMZ.com.

Sierra was [article id="1575599"]arrested December 2[/article] outside a bar near Tampa and is facing charges of disorderly intoxication, resisting arrest and violating parole. She could face more than 11 years in prison on the charges. She had been due to face a judge on Thursday (December 20).

The arrest was made in the early morning outside a bar in Ybor City, near Tampa. According to a copy of the arrest report obtained by TMZ.com, the contents of which were confirmed by a Tampa Police Department spokesperson, Sierra was booted from the Full Moon Saloon around 2:15 a.m. December 2, after she caused an unspecified disturbance while working inside the establishment.

The arrest came less than two weeks after Sierra pleaded no contest to charges of battery and possession of cocaine, stemming from an April arrest for hitting a man in the head with a glass at a Tampa nightclub. As part of her sentence for that incident, she was supposed to be completing a drug-rehabilitation program that was filmed for VH1's upcoming reality show "Celebrity Rehab With Dr. Drew."
