Stars Morena Baccarin and Ben McKenzie hope to head down the aisle once her contentious divorce is finalized, the actress reveals in court papers obtained by PEOPLE.
Baccarin, 36, is locked in a custody battle with estranged husband Austin Chick over their son Julius, 23 months. Last week, a judge ruled the boy will live primarily with his mother in New York while she shoots the Fox drama.
In her legal declaration filed Sept. 11, Baccarin opens up about her future with McKenzie, 37, and confirms they are expecting their first child together.
"Today, I am in a new committed relationship," she says. I am planning to re-marry. Also, I am 3 ½ months pregnant. "
The parents-to-be kept their romance under wraps until last weekend, when they were spotted getting cozy at Emmys afterparties.
Though neither celebrity has spoken out about the happy news, on Thursday, the O.C. vet retweeted his sister's congratulatory message: "Couldn't be happier for @ben_mckenzie and @missmorenab. Welcome to the family, Morena! Also... I'M GONNA BE AN AUNT."
