Stefani's oldest son, Kingston, was born on 26 May, 2006. Starting with their first child's name, the singer and Rossdale set a tradition of giving all of their kids two middle names. Kingston shares one of his middle names, McGregor, with his dad.
In May 2022, Stefani celebrated Kingston turning 16 by posting a throwback photo on Instagram. "I can't believe that I'm actually writing this but.... a very happy 16th birthday to my firstborn baby boy @kingsrossdale_ I prayed and I waited my whole life to be a mommy- i'm so blessed that God chose me to be yours 🙏🏻 you r so loved and we can't wait to see what happens next!! got a feeling it's gonna be good!! love u mom (gx)," she captioned a photo of her cuddling her son when he was younger.
Rossdale shared an Instagram tribute to Kingston, too. "Happy birthday sweet 16 kingston you changed my life forever and i will never be the same again .you are a force of light," he wrote. "You have bloomed like an ancient spirit. i am thrilled for what is to come. i watch with great pride and excitement . with so much tragedy in the news it makes me even more grateful for you and the inspiration you bring to those who love you . happy birthday my sweetest boy."
These days, it seems Kingston is following in his parents' musical footsteps, per his live music debut at Shelton's bar. Perhaps his recent show is the start of a professional music career.
