Murray spoke with ET in July while promoting his film, Outlaws and Angels, and the proud papa couldn't stop gushing about how becoming a father has changed his life. 

"For me, it was the greatest thing that's ever happened to me," he said. "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."

Congratulations to the soon-to-be second-time parents!
