Last night, Kristen Wiig walked onto The Tonight Show Starring Jimmy Fallon working a very familiar gravity-defying up-do and blazer. Her latest skit is a hilarious impersonation of Harry Styles - so funny that Wiig herself giggled throughout it. It ended with the comedian and Jimmy Fallon doing a brilliant rendition of What Makes You Beautiful.
It was also Fallon's debut as the host of The Tonight Show - who has taken the reins from recently retired Jay Leno - and it seems Wiig and Fallon dominated the American television ratings with 11.3 million tuning in to watch it. Hit play to watch the full clip below.
