Yes, and I realized that there's no other way for me to do it." Cohen, 57, asked whether Apa "succumbed to the old trope of, 'Wow, I'm famous, I have a lot of money and I'm just going to party.' " Apa immediately confirmed he did, and confessed that he "got lost in" the fame ofRiverdale's success.

I truly believe having Sasha saved my life," he said, before adding, "You know you have a kid and then suddenly you understand the idea of murder, you know that, like you can empathize with why someone would kill someone —" "Because you are so protective of this child," Cohen interjected. "Because you love someone so much," Apa added. "And that's the same feeling that I go, 'I love you so much more than me.' I have to sacrifice all these things for you. And that's what a good parent does." SiriusXM Apa also gushed about his son, telling Cohen, "He's great. Sasha is awesome. He's the love of my life. He's the best."

But you don't meet that many people — I don't — the same age as mine [that are fathers]." "Guess what? I'm an old dad," Cohen added. "I don't meet many guys my age with little kids either."
