But on Tuesday's The Tonight Show Starring Jimmy Fallon, the Bridesmaids star, 40, gave an interview in character as the boy-bander, 20. Only, Kristen was comically unaware of anything about Harry, so her portrayal of the beloved Brit was a little off!
"Your accent is different when I meet you in person," Jimmy said, seeming surprised Kristen's Harry character spoke like an American. But with some coaxing from the late-night host, Kristen figured things out. "I'm from…England! Really?" she asked, before picking up a momentary British accent, "Really?"
Yes, really! The Saturday Night Live alum was also blissfully unaware of One Direction's X Factor U.K. origins. "We met—at school," she said unconvincingly, telling Jimmy as Harry that she, Niall Horan, Liam Payne, Zayn Malik and Louis Tomlinson played at his home, sent "a tape to RCA," and then signed a deal with the record label.
Finally, Kristen performed a karaoke-style version of "What Makes You Beautiful," only she couldn't quite figure out how the lyrics and music synched up. After humorously making the pop song a bit too folksy, Jimmy joined in to help with the chorus.
It's pretty safe to say Kristen isn't the most die-hard Directioner, but that doesn't mean her 1D impersonation isn't pretty funny! Harry's mum Anne Cox was even impressed, tweeting a link to the clip and calling it, "Brilliant!"
