Britney was making quite the statement with her hat and ring while driving around in LA yesterday. The past few day's Brit has been looking and sounding healthier, but evidently below the surface some of her old habits are still around. Rumor has it that she booked a room at the Mondrian for Sunday night, but had to be carried out of the hotel and brought home after she was found vomiting in the bathroom at Sky Bar. A source says she was telling the staff, "I’m sorry, I’m sorry. Things aren’t going well for me at the moment.” Oh, Britney. These aren't the first post-rehab drinking rumors, but, call us naive, we're still really hoping they aren't true!
