Stefani’s fiancé, Blake Shelton, also plays an important role in her sons’ lives.
Earlier this month, the country star, 44, opened up about his relationship with the boys, saying that while being a stepparent isn’t easy, he couldn’t imagine his life without them.
“I have a stepfather in my life who’s one of my heroes. I love my stepfather and I look up to him and he’s like a father to me, so I have a good inspiration in my life for how to do this and the kind of stepdad I want to be. And I take it very serious,” he said during an interview with KFROG’s The Ride with Kimo & Heather.
“But I also have a blast with it” he added. “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.”

For a decade the hit singing competition has made dreams come true for aspiring stars – and its coaches. Now, four of the judges and host Carson Daly look back at the long-running series.
Over the summer, Shelton opened up about the balance of being both a friend and a role model to the boys.
“It’s one thing for me to be with the kids all the time and be their buddy, but you do have to consider after a while that they start to listen to things that you say,” Shelton said during a July appearance on Today. “There’s a lot of responsibility that comes with that.”
Stefani made sure to show her appreciation for Shelton last year, sharing a sweet Father’s Day post filled with images of the singer spending time with her three boys. “Thank u for helping me raise these boys!! #weloveyou! Stefani captioned the post.
