Brit Brit looked fantastically fabulous this weekend in Vegas - that sultry black dress was sizzlin'! Check her out partying at all the pre-VMA bashes, from The Palms to Pure at Caesars Palace. Joined by gal pal Alli and singer Lucy Walsh among others (including Criss Angel), Britney sure looks like she's havin' fun!BritInVegas1.jpgBritney Spears BritInVegas2.jpg
