Congrats are in order for actors Olivia Wilde and Jason Sudeikis! The couple has welcomed their first child, a baby boy named Otis Alexander!

The "Tron: Legacy" actress took to Twitter to share the news with fans, writing:

"Ladies and gentlemen, Otis Alexander Sudeikis has LEFT the building! (I'm the building)"

She also included a black and white photo snuggled with her newborn. Wilde was rather open with her pregnancy, using Twitter to provide regular updates. She has referred to herself as a "giant walking pickle."

A few weeks ago, Wilde spoke to Lucky about her pregnancy experience.

"Pregnancy does shed away all of the bulls-t," the engaged actress explained. "It gives you more empathy because you look at everyone and you think, 'You were a baby!' It also makes you feel closer to other females." 

"Pregnancy brings you into this sort of commune-you feel connected to women in a way that you never have. Not to mention the mother-baby bond that forms: He's moving around in there and no one else can tell-it's a little secret friendship."

She also told Marie Claire she wanted three kids and could not wait to become a mother.

Wilde and Sudeikis got engaged in January 2013, and revealed in October they were expecting. People was first to break the news, with a souce saying the pair were happy and excited to become parents.

The "Rush" actress told Ryan Seacrest at this year's Golden Globes they were expecting a boy and shared her cute way of remembering her due date, but it looks like he arrived a little early!

"May the fourth be with you," she said.

We are so excited for the happy couple, aren't you? Let us know your thoughts in the comments section below!
