Watch Cara Delevingne Perform ‘Crazy, Baby’ on ‘Fallon’

Cara Delevingne appeared on The Tonight Show to perform her song “Crazy, Baby.” The musician and model took the late-night show stage alongside two backing musicians, playing electric guitar and singing in the midst of piles of cables.

“Crazy, Baby” comes off Delevingne’s forthcoming LP, Not Normal , out Sept. 25. Delevingne wrote the song for her partner, British musician Minke. “I really didn’t want it to be a single, weirdly,” she told Rolling Stone . “I thought it was too obvious… But I love that song… My partner, who I’ve been with throughout this process, who’s been incredibly supportive, I was doing it to piss her off, in the sense that she hates grand gestures and she’s a very private person. The lyrics are basically like, ‘I’m sorry, but this is a love song. Get over it.’ In a cute way.”
