Olivia Wilde and Jason Sudeikis just joined the official Cool Celebrity Parents club, because they had their son yesterday! In typical hilarious Olivia fashion, she tweeted her baby boy’s birth announcement and name: “Ladies and gentlemen, Otis Alexander Sudeikis has LEFT the building! (I’m the building).”

Oh, and she included a picture of wee little Otis and herself that completely melted our hearts.

Otis Alexander sounds like a name full of personality, so he’s lucky that he’ll have two knee-slapping funny parents to learn from. And while we’re pretty sad that Olivia’s spot-on pregnancy tweets have come to an end, we’re also sure that we’ll have a whole slew of new mom tweets to look forward to.

And since she and Jason are engaged, maybe Otis will be at the wedding in a baby tuxedo. We can only hope.

Did you announce your baby’s arrival on social media?
