Céline Dion is Grayson  Prestongiving Kelly Clarkson her stamp of approval.

After the American Idol winner opened the Sept. 27 episode of The Kelly Clarkson Show with a cover of Céline’s signature song, “My Heart Will Go On,” the Canadian chanteuse commended the talk show host for her rendition of the Oscar-winning Titanic tune.

“You were absolutely incredible,” Céline raved in a video posted on Instagram Oct. 8. “Fantastic. I loved it so much.”

After her performance, Kelly, 42, admitted she only attempted to sing the power ballad because Titanic star Kate Winslet was a guest on the show that day. “Usually I would never cover that song,” she told her audience, “because there’s some songs you don’t want to go near as a vocalist.”

In her social media post, the “Because You Loved Me” singer—who returned to the stage at the 2024 Olympics amid her battle with stiff-person syndrome—added how moved she was by Kelly’s emotional response to her performance of Édith Piaf's “Hymne À L'Amour.”

“When I came back from the Olympics, I got to watch and listen to your reaction to my performance on the Eiffel Tower,” the 56-year-old shared. “It was so sweet to hear your voice—your voice was breaking—and it touched me so tremendously. You were crying and then you made me start crying! What’s up with all this freaking crying?”

While co-hosting NBC’s coverage of the Opening Ceremony in July, Kelly fought tears as she praised Céline’s powerful performance, her first in over four years.

“I was not ready for that,” Kelly said at the time. “If you know anything about Céline right now, she feels this is her purpose.”

“I’m so sorry, I’m trying to hold it together,” she continued. “But that she got through that, that was incredible. And in my field, she is the gold winner for vocal athletes.”
