Baccarin, 36, and McKenzie, 37, whose characters are romantically linked on the Fox series, were seen together at the Emmy Awards Sunday, but had not previously confirmed their relationship.

While this is the first child for the "O.C." star, the "Homeland" actress has a son, Julius, whom she welcomed with ex-husband Austin Chick in October 2013.

"The O.C." fans may recall that Baccarin had a brief stint on the show that made McKenzie famous, playing Maya Griffin for three episodes in 2006.

We wish the expectant parents all the best.
