Julia Roberts is pregnant?

Julia Roberts' Oscar nomination feels like a "thrilling bonus."

The 46-year-old actress, who took home the Best Actress trophy in 2001 for her role in 'Erin Brockovich,' is overjoyed at receiving a Best Supporting Actress nod for her portrayal of a strong-willed woman who goes back to her childhood home and her dysfunctional mother when a crisis brings her family back together in 'August: Osage County.'

The brunette beauty told People.com: "This was certainly a once-in-a-lifetime experience. And the recognition from it is an absolutely thrilling bonus. I simply could not be more excited right now."

'American Hustle' star Amy Adams, who is nominated for Best Actress, echoed Julia's sentiment.

She said: "I'm very honoured to be nominated alongside such inspiring actresses. Congratulations to the cast and crew of 'American Hustle' and 'Her,' two films that I'm incredibly proud to be a part of."

The 39-year-old star faces stiff competition from three-time Oscar winner and Julia's co-star Meryl Streep, Cate Blanchett for 'Blue Jasmine,' Sandra Bullock for 'Gravity' and Dame Judi Dench for 'Philomena.'

The British star, 79, said: "This is just the loveliest news. I'm so happy for everybody involved, and so proud to have been part of the wonderful experience that 'Philomena' has been."

Elsewhere, Irish star Michael Fassbender, 36, is thrilled to have been recognised for his work in '12 Years a Slave.'

He said: "I'm really chuffed with the Oscar nomination especially being recognised alongside such great actors. It's a real honour."

Director Alfonso Cuaron, whose movie 'Gravity' racked up 10 nominations, admitted he is especially happy for Sandra.

The Mexican movie-maker said: "These nominations are not just about single achievements, but rather the collective effort of hundreds of dedicated artists who made this dream a reality ... I am particularly moved by Sandy's nomination. She is the heartbeat of our film. She immersed herself in the part. And I thank her for her grace, her trust and her dedication to finding the truth of this character."

The awards will be broadcast live from Los Angeles on March 2, 2014.
