Ben McKenzie and Morena Baccarin are officially engaged, according to Us Weekly.
"They are very happily engaged," a source tells the magazine.
The O.C. alum, 38, and Baccarin, 37, met in 2014 on set of the FOX series, where the two play James Gorden and Leslie Thompkins.
The couple welcomed their daughter Frances Laiz Setta Schenkkan, on March 2.
Last month, Mackenzie discussed fatherhood and the meaning behind his daughter's name during Harry Connick Jr.'s daytime talk show Harry.
"Her name is Frances, after my mother," he explained at the time. "I love that name. We call her Frankie. She’s 7 months old, and the cutest thing in the world."
