Katy Perry's newest single, "Last Friday Night (TGIF)," is totally awesome. Not only is it supremely catchy, but the video is HILARIOUS. Why? It features your favorite Interwebs celebrity (Rebecca Black), Hanson, Kenny G, AND — wait for it — uber-cuties Darren Criss and Kevin McHale. Watch this video once. Or twice. We won't judge!
Who's ready for Friday?!
