The Voice coach Gwen Stefani is proudly showing off her son's eyewear collaboration with Tura. She started out in the music industry as the lead singer of the band No Doubt. They released several hit songs, including "Don't Speak" and "Hey Baby." Stefani eventually launched a solo career in 2004, with hits like "Rich Girl," "Hollaback Girl" and "The Sweet Escape." She joined The Voice as a coach starting in season 7, and returned four more times over the years. During season 19, she won for the very first time with her artist Carter Rubin.

Stefani has three children with her ex-husband, Gavin Rossdale. The No Doubt and Bush lead singers got married in 2002. Their three sons were born in 2006, 2008 and 2014. Unfortunately, the marriage didn't work out, and they ended their relationship in 2015, with the marriage legally ending the following year. Stefani started dating fellow Voice coach Blake Shelton in 2015. The couple got engaged last fall.

Aside from her voice, Stefani is also known for her fashion. Her middle son, Zuma, has gotten in on the action as well. The mother and son have collaborated on an eyewear collection called Zuma Rock. Stefani took to her Instagram Stories to show off the collection, with the caption, "Yay Zuma!!" In the photo, Zuma can be seen wearing a pair of glasses from their line. The photo is actually a snapshot of a short 15-second video ad released by Tura, the eyewear company they have partnered with. In the video, Zuma is posing for the camera. You can watch the Tura video below:

Back when the eyewear collection was first announced, Stefani told People, "If you go out and buy boy glasses, they're all the same. Zuma is a little more boyish and doesn't care as much. But with the glasses, he does because it's something he identifies with it. Everyone recognizes him with glasses. He needs the glasses." It turns out all of the Voice coach's children, including her other sons Kingston and Apollo, have shown an interest in being stylish with their clothing.

The Zuma Rock eyewear collection is a great way for Zuma to show off his passion for style. He may be only 12, but he's taken an interest in something that excites him, and his mother has clearly encouraged him to follow that passion. Considering how important fashion is to Stefani, she has likely been sharing lots of advice to her son along the way as they worked on this project together. This isn't the first time she has ventured into non-music related brands. She released a fashion line called L.A.M.B. in the early 2000's. Her own perfume followed a few years later. She also collaborated with Urban Decay on a cosmetic collection and even has her own eyewear line with both L.A.M.B. and Tura. While it's unknown if Stefani will ever return to The Voice, she is continuing forward with her lifestyle and fashion brands, and her son is coming along for the ride.
