The engaged couple welcomed a baby boy this week, with the 30-year-old actress giving fans a glimpse of their bundle of joy Wednesday, also revealing his name.
"Ladies and gentlemen, Otis Alexander Sudeikis has LEFT the building! (I'm the building)," Olivia tweeted, along with a shot of herself cuddling their little one. Olivia and Jason first announced that they were expecting a baby back in October, with the Rush star later confirming in January they were having a boy.
Not long before giving birth, Olivia told Lucky she considered her baby bump a "badge of pride," and had no problem showing it off. "I'm like, double D, hello! 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," she said.
As for her baby boy, Olivia said she enjoyed her "intimate relationship" with him while he was in the womb, adding, "He's moving around in there and no one else can tell-it's a little secret friendship."
Congrats to the couple!
