Harry Potter actress Emma attended her first Academy Awards earlier this month, where she took to the stage to present alongside Joseph Gordon-Levitt.
However, she was noticeably absent from the swanky after-show parties frequented by the rest of Hollywood.
Now we know why!
During an appearance on The Ellen DeGeneres Show this week, the actress said: "I had planned to go the Vanity Fair party but I got back to my hotel room to change, took the dress off, got into someone's coat and ended up falling asleep in the coat.
"Someone woke me and said, 'Do you want to change and go to the party?' I said, 'No, I kind of want to stay here!' I ate pizza and fell asleep. I was on English time and was a bit jet-lagged."
Emma also revealed how she'd been feeling confident about her presenting stint at the ceremony - until chatting with co-presenter Joseph right before they took to the stage.
"It was my first time at the Oscars, it was very exciting. I thought the show was amazing. I was doing fine and not nervous at all. Joseph was holding my arm before we went out and I was, 'You know what? I feel so grateful to be here and I feel amazing, really calm.' He said, 'Yeah, this is a great experience, only a billion people will be watching us...
"So I felt fine then I felt so unfine!"
Emma can next be seen opposite Russell Crowe and Jennifer Connolly in the biblical epic Noah, which arrives in UK cinemas on 4 April.
