BREAKING: BRITNEY SPEARS RE-ENTERS REHAB--AGAIN!?

Pop star continued her yo-yo relationship with rehab today by entering a rehab clinic - for the third time in a week! According to lawyers for Brit's ex-husband , who had earlier gotten a California judge to call an emergency custody hearing for the couple's two infant children, the 25-year-old singer has chosen to give rehab one more try. The lawyers also say that the custody hearing has been called off in light of Brit's decision to make another attempt at getting her life in order.Last week, Britney fled the Crossroads clinic in Aruba after only one day. Over the weekend, her wild behavior continued when she publicly shaved her own head bald in a Tarzana, Calif., hair salon. On Tuesday, Brit's reps confirmed she had decided to enter an undisclosed clinic, later discovered to be the Promises Center in Malibu, near her home and children. After less than 24 hours at Promises, Brit checked herself out. It is not yet known whether she has gone back to Promises or if she has moved on to a third rehab clinic.According to reports, Brit's children, 1-year-old Sean Preston and baby Jayden James, are currently in Kevin's custody.
