The incomparable Britney Spears was hanging out in Hollywood Monday night.

Literally!

Dressed in what appears to be a satin bed sheet of some kind and very little else, the princess must have known we were getting a bit bored with our recent articles about her.

After all, she was nice enough to provide us with a yet another nice nipple slip (see below), then later, as an encore, she flashed her rear end while getting into her car!

The mother of Sean Preston and Jayden James Federline had no bra on, obviously, but at least put on panties. Which for most is a given, but with Britney, you never know!

The latest boob and ass flashing came as Britney exited Joseph's in Hollywood last night. Deliberately or not, we can't say - but that once-fine ass was dangled tantalizingly in front of a horde photographers as she hopped into her car. A class act as always!

According to TMZ, the crowd of paparazzi could even be heard groaning as her ample back side made a very special appearance. Now that is (a) bad ass!

At least her awful hair extensions were held in place by a paisley scarf, adding a Gypsy flavor to an already whore-able ensemble. Top it off with trampy hoop earrings and a gold purse, and this MILF is ready to get crunked... Y'all!
