Jimmy Fallon had a very special guest for his second episode of "The Tonight Show": Harry Styles from One Direction.
Well ... kinda.
Kristen Wiig, who popped up as Michael Jordan on "The Late Show" last July, stopped by as the British boy bander on Tuesday. And it was AMAZING.
The spot-on hair 'do, her hilarious explanation of how they formed the band, and her completely shaky (but ridiculously awesome) performance of "What Makes You Beautiful" ... it was everything we love about the "Bridesmaids" and former "SNL" star.
