Ryan Guzman is always in “dad mode” — on-screen and off-screen. But before the actor, 38, became a real-life dad, he only played a fictional father on 9-1-1, the hit ABC series in which he has starred as firefighter and paramedic Edmundo “Eddie” Díaz since season 2 came out in 2018. Now, in an exclusive interview with PEOPLE, the dad of two and former MMA fighter expressed his gratitude to Gavin McHugh, the actor who plays his TV son Christopher, for helping him “live as a father” on the show.
“It’s a pleasure to work with him, and it’s a pleasure to call him my work son,” said Guzman, who welcomed son Mateo in 2019 and daughter Genevieve in 2021 with their mother Chrysti Ane. He continued, “In so many ways, I’ve been able to live as a father with him prior to actually being a father, and it’s taught me a lot.”
