Travis Kelce has opened up about his surprise cameo during Taylor Swift’s Eras Tour stop in London.

The Chiefs player, who has been dating Swift for nearly a year, talked about how the moment came together on the latest episode of his New Heights podcast.

Kelce said it was initially his idea to join the show at Wembley Stadium, recalling that he told Swift it would be “funny” if he “rolled out on one of the bikes” that dancers typically ride on stage during the 1989 portion of the show.

Kelce said Swift laughed, but then asked him, “Would you seriously be up for doing something like that?”

“I was just like, ‘What? I would love to do that. Are you kidding me? I’ve seen the show enough — might as well put me to work here,’” he recalled. “And sure enough, she found the perfect part of the show for me to come in.”

Kelce surprised the crowd in London last week when he appeared on stage in a tuxedo and top hat carrying Swift onstage in “The Tortured Poets Department” era of the show.

It happened on the third night of the London stops, after the brothers attended Swift’s first two shows there.

“There was no bike in case I ran into somebody else or hit one of the dancers or anything,” Kelce said. “It was the safest option.”

Kelce said his silly dance on stage was inspired by one Jim Carey does in the movie “Dumb and Dumber.”

“I always wanted to pull out this move, but I never knew like when I should pull it out where it made sense,” he said. “That’s one of my favorite moves of all time!”

All said, Kelce called it an “honor” being on the stage with Swift and her dancers.

“It was an absolute blast,” he shared. “It was such a fun, playful part of the show and it was like the perfect time for me to go up there, just be a ham and have some fun, not only with [Swift]… but the crowd and really try and get everybody excited for the rest of the show. It was awesome.”

“I didn’t disappoint Taylor, so that’s all that really matters,” he added, saying his only rule was “do not drop the 𝑏𝑎𝑏𝑦.”

“The golden rule was ‘Do not drop Taylor. Get her to the couch safe,’” Kelce said.

His brother and co-host Jason Kelce laughed, adding: “No fumbles.”
