Britney Checks Out

The Peninsula Hotel staff can breathe a sigh of relief -- Britney has left the building -- for now.

After a visit from cousin/assistant Alli Sims during the day yesterday, it appears that Little Miss Brit has obtained a proper drivers license. She jumped into her white convertible Mercedes with an unknown sidekick and took off from the hotel. She's legal now, y'all! TMZ caught her pulling out of the hotel's parking lot last night -- then she picked up a male buddy in Woodland Hills and retreated to her Malibu home.

She sure has some mighty mysterious goings-on -- but beware, Brit's back in the 'bu!
