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.
