Britney: No Bras in Oz

Britney Spears was hangin' out in Hollywood on Monday night ... all ovah the place!

Wearing a satin sheath purchased from an Emerald City garage sale, the pop mom gave peeps a peep at her pups, then she flashed her rear while getting into her car. Lil' Sean and Jayden's mama was sans brassiere, but mercifully wore panties. She's a giver.

At least her weave was held in place by her Christmas paisley scarf, bringing a Gypsy flavor to her floozetastic ensemble. Top it off with hoop earrings and a gold purse, and she's ready to party, y'all!
