Kelly Clarkson Says This Voice Coach Has the Biggest Ego

Is anyone surprised? 

By Jackie Manno

When Kelly Clarkson appeared on Watch What Happens Live with Andy Cohen in June, she was asked a series of questions about former fellow The Voice Coaches in a fun game of "Kelly's Voice of Reasons."

How to Watch

Watch the Season 26 premiere of The Voice on Monday, September 23 at 8/7c on NBC and next day on Peacock. 

After declaring Ariana Grande to be the best hugger and Alicia Keys to be the most intimidating of the Coaches she's worked with, she dropped some strong, hilarious opinions on the OG Coach, Blake Shelton. Not only did Clarkson say that Shelton was the most difficult to impress of the group (well, it's hard for Clarkson to impress him), she had another superlative for him, as well: biggest ego. 

This good-natured rib does not come as a surprise, as Clarkson and Shelton were known for their playful rivalry while on The Voice. In an interview with NBC Insider for the launch of Season 23, Clarkson dished on her favorite and least favorite parts about working with Shelton. 

“The best part about working with Blake Shelton on The Voice is you laugh a lot. He's one of the funniest people I know. He's hysterical,” she said.

“The worst thing about working with Blake Shelton on The Voice is… he is a liar. So that's hard to navigate because people still believe him when he's lying. Whatever. It's your choice. It's a choice,” she joked with a giggle.

Clarkson also opened up about Season 23 being Shelton's last on the show. "I actually have been talking to Blake a bit about this being his last season. And I'm like, 'It's not gonna hit you until afterwards. It's gonna hit you. It's been a part of your life for so long. And it's gonna hit you after,'" she said. "I think he knows that, but I also think he knows that it's time. He's been doing it a long time, and I think it's a really cool way that we all know he's leaving so we get the time to, like—I mean, I can't stand him, but I also love him. So we get the time to actually, like, lift him up and say how great he is. He is the ultimate Coach on this show. Everybody knows that. He's won the most, and he, honest to God, helps the Artists afterwards. And it's an incredible thing that he's done for so many Artists. It's a loss for The Voice."
