News of the 36-year-old actress' pregnancy was first revealed when she filed court documents on Thursday asking a judge to award her full custody of her 1-year-old-son, Julius, with her ex-husband, producer and director Austin Chick. The Homeland star asked for a proactive order since Chick is based in Los Angeles, and she lives in New York, and she will no longer fly back and forth due to her pregnancy.
Baccarin joined Gotham in late 2014 and her character, Dr. Leslie Thompkins, became romantically involved with McKenzie’s Jim Gordon at the end of the show's first season. Interestingly enough, this isn't the first time the two have worked together. She also made a one-episode appearance on The O.C. in 2006, the Fox hit that made McKenzie a star.
Baccarin and her ex-husband were married in 2011, and Chick filed for divorce on June 12, 2015, citing irreconcilable differences. As for McKenzie, he's been notoriously private about his dating life, though he did tell Elle last December that he "never had a problem being monogamous" in a relationship.
