Or will it wear her out?

One thing is for certain - all eyes will be on the 27-year-old pop superstar tomorrow night at the New Orleans Arena, where she's set to kick off her Circus tour. Sure, she performed on GMA back in December, but that was just a warm up - this is the real deal and there is so much more at stake here.

So will Queen B knock the socks off of her critics, or will she give them yet another reason to write nasty things about her? I guess we'll have to wait and see, but we know Brit has been busting her booty at rehearsals, so we have a feeling this could mark the beginning of Brit's big comeback!
