Jason Sudeikis
only has eyes for one woman ... Olivia Wilde!

The "Horrible Bosses" star was spotted taking a photo of his glowing fiance on the red carpet at the 86th Annual Academy Awards.

The mama-to-be looked stunning, showing off her baby bump in an elegant black Valentino gown. She swept her brunette locks into a simple bun, opting for natural makeup with a classic cat-eye.

The brunette beauty, who's due on May 4, is expecting a baby boy.

We are so excited for the happy couple, and we can't wait to see what their little bundle of joy looks like when he gets here!
