Chad Michael Murray is about to be a dad again.

The "One Tree Hill" actor and his wife, Sarah Roemer, are expecting their second child, his rep confirmed to Us Weekly on Monday.

Chad and the "Disturbia" actress are already parents to a 17-month-old baby boy. (In January 2015, it was revealed that Chad had secretly married his "Chosen" co-star and that they were expecting a child.)

The actor has made no secret of his love of being a father.

"For me, it was the greatest thing that's ever happened to me," he told Entertainment Tonight in July. "Having kids is a game changer and I think you're always walking around with the mentality that you want to make sure that they're proud and you want to represent them well and just be a great leader."

The "Agent Carter" star also explained how fatherhood makes him look closer at roles.

"Just last week a project came up, and just due to the content alone, it wasn't something that I [want] my son to see when he grows up," he said. "It's not the type of material and I didn't feel like the payoff was worth it. You really have to weigh each choice, but at the same time, it is a job and it is just a craft -- it's art performances. I don't take it too seriously but I also want it to creatively push me. I want to take chances and I want to do things that are going to scare the crap out of me."

Last week he poked fun at being a doting dad, sharing a photo of himself sucking a baby pacifier.
