Teigen, 35, stopped by the Tonight Show Starring Jimmy Fallon on Tuesday to discuss her new online store, Cravings by Chrissy Teigen. In a PEOPLE exclusive clip from the episode, Teigen told the story of a post-Golden Globes mishap involving Michael Keaton. The anecdote came during a round of "Best Worst First," in which host Fallon, 46, spins a wheel to determine what category his guest will answer a question in. When the spinner led Fallon to ask Teigen her best celebrity encounter, the mother of two answered, "God, I think it was after the Golden Globes — oh no, this might be 'worst.'" "I was drinking a lot and I saw somebody at the entrance holding a glass of champagne, so I just went up and I took it and I said 'thank you,' and [husband John Legend] goes, 'that was Michael Keaton.'" Fallon clarified, "It was not someone serving champagne?" "No, it was not," Teigen answered with a laugh. "God, I'm so embarrassed by it still, I could die... I took it, I drank it, and I left." getty images (2) Robes, Spices & Pans!
