Pop the bubbly, because an insider tells E! News Benjamin McKenzie and Morena Baccarin are planning a wedding! As a source first told Us Weekly Tuesday, "They are very happily engaged."

McKenzie, 38, and Baccarin, 27, met in 2014 on set of FOX's Gotham, starring as James Gordon and Leslie Thompkins, respectively. In real life, the actors welcomed a daughter, Frances Laiz Setta Schenkkan, in March 2016. Her name is a tribute to McKenzie's mother. "I love that name. We call her Frankie," he said on Harry last month, adding that she's "the cutest thing."
