Gwen Stefani’s son Apollo’s seventh birthday was Sunday and the singer celebrated the occasion by posting a carefree selfie of the two of them on Instagram.
“Happy b day bday boy !!! # apollo❤️🎂🎉🎁 ”she captioned the beautiful mother-son shot.
In the photo, Apollo sways an almost shoulder-length do, and while shining in the sun, you can see blonde heads mingling in its otherwise brown locks.

For Apollo’s sixth birthday last year, the 51-year-old and her son celebrated the occasion with her now-engaged, Blake Shelton. From day one, she shared a cute moment on Instagram – a photo of Apollo sandwiched between Shelton and her while holding an Oreo-decorated birthday cake with ‘Happy Birthday Apollo’ in rainbow icing.
‘6 years ago GOD blessed us with this little angel’ boy ‘,’ she wrote, adding the hashtags. ‘#thankyouGOD #happy birthday #APOLLO ”
Shelton, 44, has been a big help in raising Stefani’s three sons over the course of their relationship. Last March, the ‘No Doubt’ alum shared a beautiful photo of Shelton with her two oldest children, Kingston (14) and Zuma (12), after a spin on his “Friends and Heroes” tour.
While Stefani and ex Gavin Rossdale are older with her three sons, she opened up on Instagram last Father’s Day about how Shelton was a great father figure to Kingston, Zuma and Apollo.
At the time, she posted a series of photos of the country star sharing special moments with her children, from drawing and fishing to camouflage ensembles.
“Happy Father’s Day @blakeshelton thank you for helping me raise these boys !!” she wrote.
Shelton, meanwhile, recently opened up to become a stepfather to Kingston, Zuma and Apollo.
“There’s definitely nothing easy going on,” he explained in the radio program “The Ride with Kimo & Heather.” “I don’t know if it’s that hard or harder or not as hard as being a real biological parent, you know?”

“I have a stepfather in my life who is one of my heroes,” Shelton continued. “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 I can do that and the kind of stepfather I want. “And I’m taking it very seriously.”
“I can not imagine my life now without these children,” he added.
