Gwen Stefani and Blake Shelton: You thought they were the perfect couple — but — Gwen Stefani and Blake Shelton: They might not be!!!

During an interview with Seth Meyers on Late Night last night (February 21), Stefani broke down her relationship with Shelton, and explained how their dynamic translates to The Voicefor which they are both coaches. Stefani said she's ready to finally take Shelton — the show's winningest coach — down on the forthcoming Season 12, and added that the competition has even recently amounted to some couple's squabbling.

"He is in trouble this season. I’m about ready to get on that," she said. "He’s been on the couch a few nights!”

Stefani also admitted she had no idea who the country singer was before they started dating a little more than a year ago. Now, though, she's firmly in his corner.

“I didn’t even know Blake Shelton existed in the world,” she revealed. “I had no idea. I’m the biggest Blake Shelton fan now. I know all of his music.”

Oh, and she likes Shelton a lot, I guess.

"It’s so unbelievable. I love Blake," she said. "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.”
