Not a day goes by without Taylor Swift and Travis Kelce making headlines—and David Letterman has a lot to say about the cultural phenomenon that is their relationship.

“I don’t think in the history of show business or the history of popular culture we’ve ever witnessed anything like this,” Letterman said in a video shared to Instagram recently.

Speaking about the “Lover” singer, the talk show host said, “We live in a world now where all we hear is nonsense and ugliness … And now here’s Taylor Swift, who is a glowing bright light of goodness in the world, and she starts dating [Travis Kelce].” Humorously, he mistakenly said “Kelsey Grammer” instead of Travis Kelce a couple of times.

“The [Kelce] people say, ‘Oh, no, no, no, don’t bother us. We’re all caught up in football. We don’t want Taylor and football.’ And the Taylor Swift people, the Swifties, are saying, ‘Oh, we don’t want a footballer in here with [Kelce],'” Letterman added. “And I say to both camps, ‘This is such a lovely thing. Shut up!”
