Lady Gaga opened the 2013 MTV Video Music Awards with a bang -- and we bet she shut up a lot of her naysayers (we're looking at you, Perez Hilton) in the process.

Opening to a chorus of choreographed boos in a paper gown and hat, Gaga soon stripped down to a black sequined body suit and cap -- then proceeded to change outfits a slew of times, from a short blond wig and blue jacket to a scallop shell bra and white g-string. She looked as great as she sounded. As Kevin Hart put it later, "Lady Gaga got ass!"

She also got the applause she deserved for 'Applause,' winning over not just the crowd, but also viewers everywhere. Except sales for her first 'ARTPOP' single to soar after this performance, because Mother Monster killed it.

And for those of you keeping score of her imaginary, fan-created "feud" with Katy Perry? They sat next to one another without a cat fight, so let's give it up already!
