They've been together for over a year but it doesn't seem like the romance or honeymoon stage has come to an end yet for Gwen Stefani and Blake Shelton.

In a recent appearance on Late Night With Seth Meyers, Stefani, 47, couldn't help but continue to gush over her beau, whom she is once again starring on The Voice with in the upcoming season.

"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."

However, there could be tension between the two as they work together again for the first time as an official couple (they began dating the last time Stefani appeared on the show as a coach), because Stefani also admitted she isn't going to let Shelton continue his reign as the coach with the most wins on the show.

"He is in trouble this season," she said of Shelton's 5 wins out of 11 seasons. "I'm about ready to get on him."

And if he tries to get in her way, Stefani joked that he will suffer the consequences if their competition gets to fierce and causes a rift between them, claiming he's already been punished for things that have happened during episodes that were already taped.

"He's been on the couch a few nights!" She said.
