Olivia Wilde and Jason Sudeikis are parents!
The 30-year-old actress gave birth to a baby boy this week. She tweeted the big baby announcement and revealed his adorable name, writing, "Ladies and gentlemen, Otis Alexander Sudeikis has LEFT the building! (I'm the building)."
Wilde added a black and white photo of little Otis wrapped in a blanket cuddling his mama. Wilde is understandably all smiles in the adorable mommy-son photo.
This is the first child for both Wilde and Sudeikis.

Wilde and Sudeikis announced they were expecting a baby together back in October 2013 and in January of this year, the "Rush" actress confirmed they were having a son.
At the 2014 Golden Globes in January, Wilde revealed her due date (May 4) to E! News on the red carpet, telling Ryan Seacrest, "May the fourth be with you!"

Weeks before giving birth, Wilde opened up to the May issue of Lucky about her pregnancy, telling the mag, "Pregnancy does shed away all of the bulls--t. 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."

Wilde also called her baby bump "a badge of honor," but her belly wasn't the only part of her body to undergo massive pregnancy changes. "I'm like, double D, hello!" she said. "I've never been in this section of the bra store! I've been flat-chested my whole life, so it's a wonderful new world."
Wilde and her 38-year-old funnyman beau got engaged back in January 2013, just after the holidays. At the time, a source said the lovebirds were "so excited and very, very happy." Since breaking the news, Wilde was often spotted staying in shape at local fitness classes around L.A.
Wilde and Sudeikis first started dating back in November 2011.
