The 23-year-old actress famously tripped on her gown and stumbled on the stairs as she made her way to accept the Best Actress prize at last year's ceremony and she says she remembered too late the advice she had been given by her stylist.
Speaking to the new issue of W magazine, she said: "I was at the Oscars, waiting to hear if my name was called, and I kept thinking, Cakewalk, cakewalk, cakewalk.'
"I thought, Why is 'cakewalk' stuck in my head? And then, as I started to walk up the stairs and the fabric from my dress tucked under my feet, I realised my stylist had told me, 'Kick, walk, kick, walk.' You are supposed to kick the dress out while you walk, and I totally forgot because I was thinking about cake! And that's why I fell."
The 'American Hustle' actress recently admitted her fall at the Oscars has made her nervous of red carpet events.
She said: "I get so nervous before going down red carpets -particularly after that fall at the Oscars.
"I've tripped at least a couple of other times, too. I managed to forget to thank both the director and producer when I went on stage, so I wonder what was worse? I had to walk down the stairs at the wedding of my older brother recently and thought, 'I cannot fall again. I just can't."
