Olivia Wilde and Jason Sudeikis are expecting their first baby!

Wilde, 29, and Sudeikis, 38, are "incredibly happy," a source close to the couple revealed to People. Representatives of the couple have confirmed that the news is true. And we couldn't be happier for them!

The couple began dating in November 2011(though it took 6 months for them to actually go on a date, Olivia admits she was totally charmed by Jason's dancing skills), and got engaged this past January. We love Olivia's casual-cool style, so we're excited to see how she dresses her baby bump. We know she'll be a gorgeous mom-to-be!
