Let the party countdown begin.
Britney Spears has finished her stint in rehab and has left the facility.
A friend says the 25-year-old pop star "is doing fine."
She voluntarily checked herself into Promises on February 20 after a sweet weekend of hard partying in which she shaved her head.
Since then, Spears has attended AA meetings, though her stay in rehab was shorter than most. A typical stint at Promises is 45 days.
Spears has custody of the boys with visitation rights for Federline. While she was in rehab, Kevin Federline took care of the kids with help from his mom and Spears' mom, Lynne.
We suspect Britney's first stop on her way out of the clinic was 7-Eleven, where she picked up a 40-ounce bottle of St. Ides, a bag of pork rinds and a tasty mayonnaise sandwich. Then it's off to elope with Jason Filyaw.
Just kidding. We're pulling for her. Hard.
Others rooting for Spears' recovery include actor Daniel Baldwin, actress Brooke Shields (who told Access Hollywood that she'd be available to talk to the singer anytime) and music producer/rapper Timbaland.
