Olivia Wilde and Jason Sudeikis are parents! The couple welcomed their first son together this week.

The 30-year-old actress confirmed the news on Twitter on Wednesday (April 23), writing, "Ladies and gentlemen, Otis Alexander Sudeikis has LEFT the building! (I'm the building)." She also shared a black-and-white photo of her cuddling her newborn son.

This is the first child for both actors. They announced their pregnancy back in October, nine months after Sudeikis proposed.

Back in 2012, Wilde told USA Today she is "totally inspired by the idea of being a badass working professional mom. I'm so into my dog. I can't imagine how I will smother my child." And last year, in an interview with Marie Claire, she hinted that one might not be enough: "I'm open-minded about how many, but three is like a little party."
