Cara Delevingne performed her song "Crazy, Baby" on The Tonight Show Starring Jimmy Fallon, playing electric guitar and singing alongside two backing musicians amid piles of cables on the late-night stage.

"Crazy, Baby" appears on Delevingne's forthcoming LP, Not Normal, due out Sept. 25. Delevingne wrote the song for her partner, the British musician Minke, and she initially resisted releasing it as a single.

"I really didn't want it to be a single, weirdly," Delevingne 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."

Sitting down with Jimmy Fallon, Delevingne discussed the album and her role in the upcoming film Club Kid. She also recounted the night Stevie Nicks attended one of her concerts in Los Angeles.

"She came, I thought I saw her in the crowd, and then I felt like I performed the whole thing to her," Delevingne shared. After the show, she sat down with Nicks — and the encounter left her stunned. "I'm not sure what I said," Delevingne said. "I think I blacked out. But she was crying. She cried. And she gave me this ring off her finger."

Delevingne showed Fallon the ring, then explained its significance. "She said she bought it when she was on tour way back when and that she felt the pain in my music and that she really related to it and heard it," Delevingne said. "That was a really crazy moment."

The Fallon appearance caps a run of live dates for the model and musician. Delevingne will perform at All Things Go 2026 in Forest Hills, New York, on Sept. 25 — the same day Not Normal arrives. She is also booked for Primavera Sound Buenos Aires in November and Primavera Sound São Paulo in São Paulo, giving the album its first international showcase stages.
