Chrissy Teigen once confused Michael Keaton for a champagne waiter after the Golden Globes.
The 35-year-old model has admitted that her post-Globes encounter with the Hollywood star was her most embarrassing encounter with another celebrity.
Asked about her best celebrity encounter on 'The Tonight Show Starring Jimmy Fallon', Chrissy shared: "God, I think it was after the Golden Globes - oh no, this might be worst ..."
Chrissy - who has Luna, four, and Miles, two, with husband John Legend - then recalled the embarrassing details of her meeting with the movie star.
She said: "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 [John] goes, 'that was Michael Keaton.'"
After realising her mistake, Chrissy made a quick exit.
She said: "God, I'm so embarrassed by it still, I could die ... I took it, I drank it, and I left."
Chrissy - who has been married to John since 2013 - previously admitted to drinking too much at one point in her life.
During an interview in 2017, Chrissy confessed to "making an a**" of herself in front of people she respected.
She explained: "I was, point blank, just drinking too much.
"I got used to being in hair and make-up and having a glass of wine. Then that glass of wine would carry over into me having one before the awards show. And then a bunch at the awards show.
"And then I felt bad for making kind of an a** of myself to people that I really respected. And that feeling, there's just nothing like that. You feel horrible. It's not a good look for me, for John, for anybody."
