Troubled pop star Britney Spears has completed her stint at a rehabilitation center and is "doing fine," a magazine reported on Wednesday.
Spears "has been released by the Promises Malibu Treatment Center after successfully completing their program," her manager, Larry Rudolph, was quoted as saying by People magazine's website.
A friend also said Spears was "doing fine," the magazine said.
Spears attended Alcoholics Anonymous meetings during her nearly one-month stay, though a typical program lasts 45 days, the celebrity magazine wrote.
There was no immediate comment from the center, which promises strict privacy for prospective patients at its gated estate on the Pacific coast.
Spears checked herself in on February 20, after she shaved her head at a hair salon within view of paparazzi, and then briefly checked out again the next day.
But she returned to the center in Malibu reportedly after her estranged husband, Kevin Federline, threatened a custody battle over their two children, the magazine said.
Federline has visited the pop princess several times at the facility with their sons, most recently last weekend, and is "supportive" of her recovery, according to People.
During her time at the rehab center, Federline reportedly took care of the two boys with help from his mother and Spears' mother.
The singer stunned staff at a suburban Los Angeles beauty salon last month by walking in and demanding they cut off her mane of brunette hair extensions.
When staff refused, Spears grabbed a set of clippers and shaved her head to the delight of a crowd of paparazzi who had gathered outside to watch.
Spears has never been far from the media spotlight ever since she announced plans to divorce Federline last November.
Entertainment media have followed her every misstep since then, including her appearance in public in a short dress without panties, clearly evident in unflattering photographs which quickly flew over the Internet.
