Olivia Wilde And Jason Sudeikis

Olivia Wilde and Jason Sudeikis are first-time parents after the actress gave birth to son Otis Alexander on Wednesday.

Wilde posted a selfie with her new bundle of joy on twitter, writing, "Ladies and gentlemen, Otis Alexander Sudeikis has left the building! (I'm the building)."

Little Otis arrived 10 days early.

Beating the due-date means Wilde can head back to work soon -- she'll start in a new HBO series produced by Martin Scorsese and Rolling Stone Mick Jagger that takes place in the 70s, when punk and disco music were on the rise.

The series is set to begin production this summer.
