As Friday night’s guest, Rebel Wilson landed at the stages of The Tonight Show to engage in a beat battle challenge with the host.
After clarifying that this was not a “beat-up” challenge, which the Australian actress seemed hesitant about, Fallon explained the rules: A random beat will play, and we’ll take turns singing songs that fit over that beat until the buzzer goes off. There are no winners or losers. That being said, if you can’t think of a song, you lose.”
Wilson declared that the game sounded “hard,” though she threw herself into it full steam ahead. For the first beat, Fallon sang “Some Nights” by the artist Fun. Wilson jumped in with “Work It” from Missy Elliott. When the beat changed, Fallon launched into “MMMBop” from Hanson.
Fallon claimed that the set was a tie, but the judges gave it to Wilson. Gaining even more confidence, she announced, “I feel like we should make it harder.” Since Valentine’s Day is coming up (and also the release of Wilson’s Isn’t It Romantic — though Wilson didn’t mention that), she decided that the songs in the next round “have to be about love.”
Among the love songs, Wilson sang “I’m Yours” from Jason Mraz and Fallon flew in with “You Make My Dreams” by Hall and Oates. Getting her groove on, Wilson continued to own the stage as she dove into more loved-up tunes.
From director Todd Strauss-Schulson, the Wilson-starrer Isn’t it Romantic releases Feb 13. The film also features Liam Hemsworth, Priyanka Chopra and Adam Devine.
