Carrie Underwood promises there is no bad blood between her and Nikki Glaser.

Last month, online chatter revved up after the comedian appeared on “American Idol” as a guest judge, with fans speculating that there was tension between Underwood and Glaser.

One fan wrote on Facebook, “Very obvious. Esp from Carrie. We have the extremes of 2 women. Carrie, no matter how talented, ever since I saw her on American idol, I pick up a really cold vibe,” according to the Daily Mail, while another wrote on X: “The tension between Carrie and Nikki is KILLING me lmaoo.”

Glaser filled in as fourth judge for the show’s first-ever Taylor Swift-themed night on April 27.

Fans were convinced that Underwood did not like sitting next to Glaser, a huge Swiftie, and that Underwood scowled whenever Glaser spoke.

The country singer, 43, dismissed the theories on Sirius XM’s “Highway Mornings with Cody Alan” earlier this week, insisting that there was “no beef” between her and Glaser, 41.

Alan mentioned fans’ reactions, suggesting that some people like stirring up trouble.

“I’m like, ‘Do you know Carrie Underwood?’ Like, she’s never going to be a mean person,” he said. “They want to cause a catfight over the smallest little thing.”

The “Before He Cheats” songstress responded by saying she’s “very used to that,” and gushed about Glaser.

“And I think she did such a great job because it’s not an easy thing to come sit behind that desk and try to think of constructive things to say,” she said. “And I don’t know, I feel like she did everything wonderfully. But no, there’s no beef. I have no beef.”

Underwood has developed a thick skin as a judge on the long-running show.

She clapped back after being booed by the “American Idol” audience during a show last March.

“Boo me. I don’t care,” the country singer wrote on X while the episode was airing.
