Britney Spears has left rehab after almost a month's worth of treatment.

The singer's manager Larry Rudolph confirmed the news in a statement late, last night (March 20). It read, "Britney Spears has been released by the Promises Malibu Treatment Center after successfully completing their program."

And it seems life on the outside world will be a lot less complicated for Brit than before she checked in on February 22.

She has reportedly come to an out-of-court agreement with ex-hubby Kevin Federline over finances and their nippers.

According to a report in The Sun, the singer has agreed to pay K-Fed a lump sum of one million quid, plus half of her earnings for the time they were married. It claims Britney has also agreed on joint custody of their sons Sean Preston and Jayden James.

A mate of the singer told the tab, "She and Kevin started talking again and he's been a tower of strength for her.

"Her time in rehab has given Britney a lot of time to think, and has shown her Kevin loves his kids and is a good dad."

Let's hope this is a happy ending at last, for Brit...
