VIDEO: Watch Rainn Wilson Get Quizzed on How Well He Knows 'The Office' Superfan Billie Eilish

Fans of The Office will remember when Dwight Schrute actor Rainn Wilson quizzed Billie Eilish on the fan-favorite series, only to prove that she's a complete superfan. In fact, the 53-year-old actor found out that the Grammy nominee has watched the show start to finish twelve times! That's some impressive binging.

So, when Wilson appeared on A Little Late With Lilly Singh this week, the host quizzed him on how well he knows Eilish. Well, well, well. How the turntables...

Singh started off asking Wilson, "Billie was born the same year as which handheld musical technology?" The actor didn't skip a beat and said, "iPod." Correct! The next question was, "Billie has a song with the same name as which television show of yours?" This was a little tougher for Wilson, but he got it correct with "Six Feet Under."

The final question was, "Which Canadian musical heartthrob was Billie's first love?" Wilson had to narrow down by saying, "It's not Drake. I can see that in your eyes." He then shot back, "It's the Biebs!" Correct!

After getting all of the answers correct, Wilson admitted he must now be Eilish's stalker. But considering how much the songstress is obsessed with The Office, we don't think she'd find this a bad thing.
