Britney Spears celebrates her 26th birthday with pals Paris Hilton and Alli Sims. The trio first popped by a Sharon Stone-hosted party in Bel Air, CA. Brit, as usual, sports a tragic outfit consisting of a revealing black mini, studded fur coat, and a choker necklace.

"Hey, y'all! It's my birthday!"

Brit, flanked by Sam Lutfi and cousin Alli, laughs at some silly pictures. Speaking of silly, look at her roots!

We have a funny feeling that Paris has decided to once again hang with the fallen pop star in order to improve her own tarnished image.

After a relatively mild night on the town, Britney leaves the hotel with her pooch London in tow. Apparently, nobody was kind enough to buy Ms. Spears a new pair of boots for her birthday.
