Blake Shelton is taking his stepfather duties very seriously.

Appearing on "The Ride with Kimo and Heather," the country music star, 44, opened up about his relationship with Gwen Stefani and how becoming a stepfather to her three children has impacted his life.

"I take it very serious, but I also have a blast with it," Shelton told the interviewers. "I don't take it so serious that I'm not enjoying this time because I really am, especially now that we're five years into this thing. I can't imagine my life without these kids now."

"I have a stepfather in my life who is one of my heroes," the singer added. "I love my stepfather and he's like a father to me, so I have a good inspiration in my life on how to do this and the kind of stepdad I want to be."
