LOS ANGELES - Britney Spears has left rehab.
The pop star's manager says she has successfully completed a program at the Promises rehabilitation facility in Malibu, California.
The 25-year-old singer entered the program February 22nd, after a bout of bizarre behavior that included shaving her head, getting tiny lips tattooed on her wrist and beating a car with an umbrella.
Spears' activities have been weekly magazine fodder since she filed for divorce from aspiring rapper Kevin Federline in November.
The two have joint custody of their sons, Jayden James, six months, and Sean Preston, 18 months.
Federline and the children reportedly visited Spears during her treatment.
Federline, an aspiring rapper who released his debut album in November, will celebrate his 29th birthday today with a party at West Hollywood nightclub Eleven.
A second bash will be held at Pure Nightclub in Las Vegas on Saturday.
Spears has not disclosed why she sought treatment at Promises, which offers detox, counseling and 12-step programs.
A 30-day stay at the plush, oceanfront facility costs 48 thousand dollars.
