Carey Mulligan has revealed that she is staying off the alcohol for the rest of the awards season.
The actress admitted that she drank to much at the Independent Film Awards at the end of 2009 because she didn't think that she was going to win.
Speaking at the Academy Awards Nominees Luncheon in Beverly Hills she said: "I was at the Independent Film Awards in London and I was hammered,"
"I didn't think I was going to win, so I was like 'ah whatever'. Then I got up there and it was lucky I kept it very short and got off the stage, so since then I've been very well behaved."
Mulligan has shot to fame with her performance in An Education, a performance that has seen her bag her first Best Actress Oscar nomination.
But she faces tough competition with Sandra Bullock, Helen Mirren, Gabourey Sidibe and Meryl Streep all fighting it out for the award.
She back on the big screen later this year when Wall Street: Money Never Sleeps hit the big screen.
She stars alongside Michael Douglas, Josh Brolin and Shia LaBeouf in Oliver Stone's sequel.
