WATCH: Kristen Wiig as Harry Styles on 'The Tonight Show'

The Tonight Show hosted one heck of a lineup on Tuesday night with guests including Jerry Seinfeld and Lady Gaga, but the true star of the night was a surprise visit from Harry Styles of One Direction (or was it Kristen Wiig?).

Wiig has a habit of giving up her interview time with Jimmy Fallon to make way for more interesting guests. She showed up as Michael Jordan when Fallon was the host of Late Night and continued the streak with her awesomely oblivious impression of Styles. What makes these so perfect is that Wiig doesn't seem to know a single thing about the people she impersonates and improvs the entire interview. With her Harry Styles impression, Fallon could barely keep it together long enough to finish the interview. 

Watch this gorgeous piece of comedy below:
