Did Britney spend her last night at Promises attending an AA meeting in Topanga? It's hard to tell if she was in one of the SUVs she normally takes to the meetings, but let's hope her end to rehab doesn't mean an end to her treatment.

UPDATE - Our photographers just saw a car leave Kevin's house with the back windows covered (as Kevin usually does when he has the kids in the back seat) ... And we're hearing rumors about Britney's whereabouts in LA. As soon as we can confirm anything, we'll let you know ...
