Gwen Stefani’s very grown-up-looking son Zuma shows off ‘beautiful’ musician girlfriend

Gwen Stefani‘s son Zuma is still basking in his 18th birthday celebrations, and what better way to keep the party going than with his “beautiful” girlfriend?

The musician, who turned 18 on August 21, shared a sweet photo of himself and his singer-songwriter girlfriend, Theran Rose, after she surprised him with a very thoughtful birthday gift.

In the photo, Zuma and Theran are sitting beside each other on a couch, with a “gorgeous” Fender Telecaster taking pride of place on his lap.

“Thank you to my Beautiful Girlfriend @theranrosemusic for getting me this gorgeous @fender telecaster. I will be using this ol’ beauty for many adventures and memories to come!” Zuma captioned the post.

While it’s unclear how long Zuma and Theran have been dating, he first appeared on her Instagram in a February post celebrating Valentine’s Day, while he debuted her on his Instagram in May, revealing her as his prom date.

The couple is very vocal about their love for each other. In a birthday tribute to Zuma, Theran shared a compilation video of moments throughout their relationship alongside a heartfelt message.

“Happy birthday my sweet boy!! I’m so so incredibly proud of you and all you’ve accomplished. I can’t believe you’re eighteen, and I can’t believe how much you’ve grown,” she wrote.

“Never stop chasing your dreams baby cause I know you’ll reach the stars, and I’m so grateful that I’m able to watch that personally.”

She added: “You’re the sweetest, kindest, funniest boy I know. I love you so much, Happy birthday Suma @zuma_rossdalemusic.”

One post wasn’t enough, as Theran later added more photos of her and Zuma, which she captioned: “Final post……Looking back at these photos, videos and memories with you Zuma make me realize how lucky I am to have such a caring person in my life!! 

“You bring so much light and love to everyone your around Zuma and I’m so incredibly grateful to call you mine and to keep making different memories each time I see you. 

“I love you from the bottom of my heart and can’t wait to see where our futures lead us. I love you – Your Cowgirl.”

Theran wasn’t the only person shouting out the birthday boy, as his mom got in on the action too.

The No Doubt singer, 56, shared a touching Instagram montage filled with memories from his childhood through to his teenage years.

The photos included adorable baby and toddler moments alongside candid family snaps, including footage of Zuma losing a baby tooth and spending time with his famous mom.
