Olivia Wilde Expecting A Baby Boy With Jason Sudeikis

Olivia Wilde announced some big news at the Golden Globe Awards on Sunday (Jan. 12).

The mom-to-be revealed that she and fiance Jason Sudeikis are expecting a baby boy -- and that he's due to arrive in May.

“May the fourth be with you,” she told E!'s Ryan Seacrest, explaining that’s how she remembers the date.

Wilde, 29, wowed at the awards show in a skintight, sequined emerald-green Gucci dress, allowing her bump to take center stage.

“Until about a week ago, I just looked fat,” she told People of her wardrobe choice. “I wanted to be like, ‘I’m not fat, I’m pregnant!’”

She even joked about her sexy look on Twitter, writing:

As for her baby boy-to-be, Wilde said her son was bouncing around in her belly all night.

"He was kicking the whole time, going, 'Where are we?!'"

Congrats to Olivia and Jason!
