Needless to say, we saw a LOT of amazing performances at last night's 2013 MTV VMAs. Lady Gaga opened the night with a stunningly theatrical rendition of "Applause," Katy Perry closed things out with a boxing/"Rocky"-esque "Roar" performance under the Brooklyn Bridge, and need we remind you that we saw *NSYNC REUNITE ONSTAGE during Justin Timberlake's Video Vanguard medley?? (No, we didn't think we had to remind you about that. It's burned in our brains for allllllll of eternity. Along with Justin doing the "Mirrors" slow-slide dance. #Sexy.)
