Sandra Bullock: I'm Getting "Liposuction" Before the Oscars!

Sandra Bullock says she wasn't aware that she had nabbed a Best Actress Oscar nomination Tuesday morning.

When the nominations were announced in Beverly Hills, "I was asleep like a little tiny baby," the first-time nominee, 45, said in a telephone interview on the Today show Tuesday.

Of her nomination, she said, "I think it's just so big that maybe when I am about 74, I'll have that moment in a grocery store with my walker and go, 'Oh, my God! This year has been mind-blowingly amazing!'"

She said she has plenty of preparations to make before the March 7 show at Hollywood's Kodak Theatre. "I've never done this before!" she told Matt Lauer.

She then joked, "I do believe some liposuction is in order, a very strict diet regime, and I will acquire a very light English accent. I was going to say that I should start wearing glasses, but I already wear glasses, so I am already sort of there."

Bullock -- best known for romantic comedies like Miss Congeniality and Two Weeks Notice -- has won a Golden Globe and Screen Actors Guild award for her role as Leigh Anne Tuohy -- a blonde Memphis mother who takes in a homeless, high-school student -- in The Blind Side, which is based on a true story.

In a statement to the Hollywood Reporter, Bullock said: "I'd always assumed that the road to Oscar was planned. I thought people chose projects that were considered 'Oscar-worthy.' No one wanted to make this film. I didn't want to make this film for the better part of the year. Everyone is as blindsided - can I say that? - as I am."

Ironically, the day before her receiving her Oscar nomination, Bullock received a worst-actress nomination for All About Steve from the Golden Raspberry Foundation, host of the annual Razzies.

If Bullock walks home with both awards (the Razzies take place the night before the Oscars), she will be the first person ever to win a Razzie and an Oscar in the same weekend.
