After a very public downward spiral, and just under 30 days in rehab, Britney Spears is back at home. Britney checked out of Promises late last night, we can only assume in order to avoid the daytime paparazzi frenzy. Her manager released a statement saying that Britney successfully completed her program and asks that everyone respect her privacy at this time. She still has a long way to go and custody issues to work out with Kevin whose birthday is today! How nice of Brit to be home in time. K-Fed also cancelled his big party tonight - perhaps to support her homecoming. We just hope for Britney to continue on the road to a full recovery, and a big comeback.
