Ben McKenzie and Morena Baccarin's Relationship Timeline

Actors Ben McKenzie and Morena Baccarin have Gotham to thank for their love story.

The two met on the set of the Fox series, on which McKenzie starred as Detective James Gordon and Baccarin as Batman's ally Leslie Thompkins. Though Baccarin originally had a recurring role, she was promoted to the main cast in season 2.

Life imitated art when both the actors and characters became romantically involved; McKenzie and Baccarin showed off some PDA at the 2015 Emmys, and their relationship was confirmed shortly thereafter, followed by a pregnancy announcement. Baccarin's character also became pregnant around the same time the actor announced she was expecting her first child with McKenzie.

Gotham ended its five-season run in 2019, but McKenzie and Baccarin's relationship has kept going strong. From their initial connection on set to the significant date of their wedding, here's what to know about Ben McKenzie and Morena Baccarin's relationship timeline.
