We've all seen Britney Spears surrounded by paparazzi - they're just not usually this hot! Last night, Britney broke out the most outrageous outfit she could find and headed out to the Green Door to shake her tail (
literally!). Sexy as she was looking, however, we honestly had a hard time taking our eyes off Sam, Alli, and Lucy - and their X17 costumes!
Of course, Brit wasn't done breaking out the Halloween costumes - wait'll you see what she wore next!

We love your outfit, B...

But

Alli's has its charms too!
The big question: Who's hotter?
