In February, Shelton opened up about being a stepfather to Kingston, Zuma and Apollo, whom Stefani shares with ex Gavin Rossdale.

During an interview with KFROG's The Ride with Kimo & Heather at the time, Shelton said there is "definitely nothing easy" about being a stepparent.

"I don't know if it's as hard or harder or not as hard as being an actual, biological parent, you know?" he said. "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."

"But I also have a blast with it, I'm not gonna lie," added Shelton. "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," he said.

Stefani shared a collection of images to her Instagram feed showing Shelton spending time with all three boys over the years to commemorate Father's Day 2020 last year. "Thank u for helping me raise these boys!! #weloveyou! G❤️K❤️Z❤️A gx," Stefani wrote in the post's caption at the time.
