LATEST: Britney Spears has left rehab after completing a four week program at a Malibu, California treatment centre and has pleaded with the world's media to respect her privacy. The troubled pop star - who checked into the Promises rehabilitation centre last month (FEB07) - was being treated for substance abuse, but it is unclear exactly when the 25-year-old left the facility. Spears first checked into Eric Clapton's Crossroads treatment centre in Antigua on 14 February (07), but left the following day (15FEB07). She checked into Promises on 19 February (07), before leaving the next day (20FEB07), and then re-checked herself in on 21 February (07). The TOXIC singer's treatment came after months of hard-partying following her split from husband Kevin Federline in November (06). Days before she checked into Promises, Spears stunned fans by shaving her head and getting a tattoo of a pair of lips on her wrist. In a statement issued late last night (20MAR07), Spear's manager LARRY RUDOLPH confirmed her exit from rehab and asked for the press to keep their distance while she settles back into life at home with her two babies Sean Preston and JAYDEN JAMES. He says, "(She) has been released by the Promises Malibu Treatment Centre after successfully completing their program. "We ask that the media respects her privacy as well as those of her family and friends at this time."
