Rossdale shares his sons Kingston, 17, Zuma, 15, and Apollo with ex Gwen Stefani, 53. He is also dad to daughter Daisy Lowe, 34, from a previous relationship.

Last summer, the musician shared a sweet shot on Instagram surrounded by all four of his kids, posing beside Rossdale at a patio table as they snapped the family photo from his Los Angeles home.

"Welcome to my world. the best few weeks at home with my better versions of me," he captioned the photo. "Oh the joy they bring. and yes there's chewy bottom left. and our super hero apollo. My love is indeed ocean sized."

In July, Rossdale appeared on the podcast Not So Hollywood, chatting with host Adrianna Costa about how he and Stefani are each raising their three sons with differing views, which Rossdale said offers their boys an "incredible perspective."

Asked how Rossdale and Stefani make co-parenting work for their sons, the singer explained that the two don't exactly co-parent, they "just parent."

"I think you can go one of two ways — you can either do everything together and really co-parent, and see how that goes — or you can just parent. And I think we just parent," he began.

"We're really different people ... I don't think there's much similarity in the way we bring them up but I think that gives them an incredible perspective to then choose which pieces of those two lives they'd like to inherit and move on with and which part of themselves come out of the whole process," he continued.

"Because that's what's important is to give them a wide view of things and we definitely have some particularly opposing views so I think it'd be really helpful for them to make their own minds as individuals."
