Break out the blue! Olivia Wilde and Jason Sudeikis are expecting a baby boy.

The pregnant actress chatted with People Magazine last night at the 2014 Golden Globe Awards, and she revealed that she'll be giving birth to the couple's first son at the end of April.

Wilde showed off her baby bump in a sparkly green Gucci gown, and joked to Ryan Seacrest, “It’s great — I’ve never had boobs before! Until about a week ago, I just looked fat! I wanted to be like, ‘I’m not fat, I’m pregnant!’”

Wilde and Sudeikis have been together since 2011, and they got engaged in January of 2013.
