Gwen and Blake's Love Story
The Voice coaches, who've been dating for five years, first met on the set of the NBC singing competition. In 2015, both Shelton and Stefani were going through divorces. Shelton split from his wife of four years, Miranda Lambert. Stefani, who rose to fame as the lead singer of No Doubt, split from Gavin Rossdale after 13 years of marriage.
"Gwen saved my life," the Oklahoma native said in a 2016 interview with Billboard. "Who else on earth could understand going through a high-profile divorce from another musician? You can't even imagine the similarities in our divorces."
The "God's Country" singer has also helped Stefani raise her three children: Kingston, Zuma and Apollo. The singer praised Shelton in a 2020 Father's Day post.
"Happy father's day Blake Shelton. Thank u for helping me raise these boys!," read Stefani's social media post, which accompanied eight photos of Shelton doing co-parenting stuff.
Shelton has credited Stefani for turning his life around.
"I don't want to remember what I was like before Gwen, actually," Shelton told Entertainment Tonight.
Stefani echoes the country singer's sentiment.
"Like, we're just having the time of our lives, and we never expected that this late in our lives, so we're just trying to savor every moment together, and just to be back on The Voice as well -- not to change the subject -- but working together again has been really fun, and I love being here and I love being with him," Stefani said in a 2019 interview with Entertainment Tonight.
Shelton and Stefani are currently on season 19 of The Voice alongside fellow coaches John Legend and Kelly Clarkson.
