Jessica Sierra to spend a year in rehab

Former American Idol contestant Jessica Sierra is heading back to rehab - for a year.

The singer escaped jail - but was instead ordered to complete a longer stay in rehab after pleading guilty to charges of disorderly intoxication and obstruction of an officer.

The charge also includes two years of probation, stemming from an incident in a bar in Florida last month.

Sierra, who was the tenth-place finalist on the fourth season of American Idol, allegedly got into a heated exchange with bar staff and police after she was kicked out of the bar.

The pregnant singer was also reportedly sick in a police car and offered officers sexual favors in exchange for her release.

The arrest violated Sierra's probation from an incident in April of last year that resulted in charges of cocaine possession and felony battery, after she allegedly hit a bar patron in the head with a glass.
