Gwen Stefani shares sweet rare photos of her son on his 15th birthday

Gwen Stefani celebrated her son Zuma’s 15th birthday by sharing rare photos of him with her fans.

The pop superstar marked her middle child’s big day by posting an adorable compilation of snaps in an Instagram video.

Set to Zach Bryan’s song ‘Something in the Orange’, the clip shows pictures of Zuma from childhood to the present day and there’s even a cameo by his stepdad, Blake Shelton.

“Happy 15th birthday Zuma!!! We love u more than anything,” the mum-of-three captioned the post.

Stefani shares Zuma and her other two children, sons Kingston, 17, and Apollo, nine, with ex-husband Gavin Rossdale, whom she divorced in 2015.

The hit-maker occasionally shares pics of her boys on social media and posted similar photo compilations to celebrate Kingston and Apollo’s birthdays earlier this year.

Stefani's eldest son, Kingston, recently made waves after performing his first gig at stepdad Shelton's bar in Oklahoma.

It should come as no surprise that the teen has a knack for music as he appeared to enjoy his debut set at Ole Red in Tishomingo, Oklahoma on 11 August.

The set was very stripped down and he performed with only an acoustic guitarist and keyboard player.

Later on in the evening, Stefani joined Shelton on stage for a rendition of one of her most well-known tracks, ‘Don’t Speak’.

Meanwhile, Rossdale, who is the lead singer of the post-grunge band Bush, appeared on the podcast Not So Hollywood in June where he explained to host Adrianna Costa about how he and Stefani raise their kids following their split.

The musician said that he and the The Voice judge have different views, which he thinks offers their three sons an ‘incredible perspective’.

And Rossdale said they don’t exactly co-parent’, instead they ‘just parent’.

He explained: “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."

Although Rossdale said he and his ex-wife are ‘really different people’ it works in their children’s advantage.

“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 shared.

"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."
