"I thought I was managing my expectations, but on hearing the news I discovered new and unfamiliar vocal tones. Perhaps I should do another musical," said the Mamma Mia star.

The star will go up against George Clooney (Up in the Air), Jeff Bridges (Crazy Heart), Jeremy Renner (The Hurt Locker) and Morgan Freeman (Invictus).

Freeman said: "This is my fifth nomination and I'm more proud of that than all the rest of it, I think. Getting nominated, to me, that's the plateau.

"After you're nominated, it's like a crap掷骰子 shoot, it's like throwing dice骰子."

In the best actress category, Sandra Bullock also picked up her first nomination for The Blind Side, along with Mulligan for An Education and Gabourey Sidibe for Precious.

Sidibe, who has been nominated for her first leading role, said: "As soon as I heard, I jumped up and down and for some reason I kept screaming, 'I'm gonna get a car, I'm gonna get a car.' I don't know why."

They will battle it out with Academy Award winners Dame Helen Mirren, for The Last Station and Meryl Streep, for her role in Julie & Julia.

There are also nods for Penelope Cruz (Nine), Vera Farmiga (Up in the Air), Maggie Gyllenhaal (Crazy Heart), Anna Kendrick (Up in the Air) and Mo'Nique (Precious) in the best supporting actress category最佳女配角.
