Britney Spears tour concert costumes dance Britney Spears tour concert costumes dance

I know we've all seen Brit's Circus costumes a million times, but that doesn't mean we can't continue to mention how smokin' hot she looks in them! After snapping these shots of the pop princess performing at the MGM Grand Garden Arena in Las Vegas last night, we think all the Britney haters will have a hard time talking smack about her now!

Oh, and guess who we spotted in the audience? Brit lovers Paris Hilton and Doug Reinhardt, of course!
