Britney -- What an Ass!

The mother of two was spotted outside Joseph's in Hollywood last night, where she gave the wildly snapping paparazzi an eyeful of her once taut tush as she hopped into her car. The crowd of paps can even be heard groaning as her ass made its very special appearance. At least she wore panties this time!

Britney did manage to keep one embarrassing feature somewhat covered though -- holding her hands over her nasty hair extensions on her way into the restaurant/club.
