Britney Spears is out of rehab

Britney Spears is out of rehab!  After 28 days of treatment, the "Toxic" singer left Promises rehab facility late on Tuesday night.  According to her TMZ; her manager, Larry Rudolph, said she checked out after "after successfully completing their program."

News broke earlier this week saying that Spears would check out of the facility a bit early to attend her estranged husband, Kevin Federline's, birthday party.  Today, Page Six is reporting that the party scheduled to be held in Hollywood tonight at Eleven nightclub has been cancelled.  Evidently some of his sponsors bailed.

Eleven was looking for a weekly magazine to sponsor the party. Evidently, none jumped at the chance. Then, the smaller sponsors allegedly pulled out. But a rep for Federline assured Page Six it was Kevin who canceled the event, though his bash Saturday at the Pure nightclub in Las Vegas is still on. "He decided that one party was enough," said his rep. "Kevin is just focusing on his family right now."

So in other words he can't have a party out of fear that Britney might fall off the wagon?
