The 47-year-old singer was asked about her romance with her fellow Voice coach boyfriend, and after a second of deliberation she said: “It’s so unbelievable. I love Blake. He’s the most incredible guy. Everybody loves Blake and that’s the thing, there’s no way around it. He’s just a sparkly, happy, amazing person.”
Stefani is returning to the singing show for its 12th season, and she’s determined not to let Shelton’s team win this time.
Despite the fact he’s the most successful Voice coach, with five out of 11 wins, Stefani said: “He is in trouble this season. I’m about ready to get on him.”
The late-night host asked whether competing on the show had ever caused a rift in their relationship, to which she quipped: “He’s been on the couch a few nights!”
Although the couple have been dating since November 2015, Stefani admitted she wasn’t exactly a fan of the country star, 40, before they began working on the hit show in 2014.
“I didn’t even know Blake Shelton existed in the world,” she revealed. “I had no idea.”
But that’s not the case anymore!
“I’m the biggest Blake Shelton fan now,” she said. “I know all of his music.”
