The 44-year-old, who previously won Academy Award for Best Supporting Actress in 'The Aviator', said she has "butterflies" in her stomach, reported Contactmusic.
"A lot of effort goes into effortlessness of walking up that marathon red carpet. I wake up with butterflies in my stomach. You never know the outcome. It has been an extraordinary year in films, so to be at the banquet is a privilege," she said.
The prestigious 86th Academy Award will take place on March 2 in Los Angeles.
