Kylie Kelce really is a Swiftie.

The mom of three, 32, attended a Philadelphia Eagles charity event with her husband, Jason, on Wednesday and was captured on camera belting out Taylor Swift’s “Love Story” while carrying three pitchers of beer.

The X (formerly Twitter) account of the retired athlete and his brother Travis’ podcast, “New Heights,” shared the hilarious clip and wrote, “Sing it Ky!!!”

The clip caught the attention of the pop star’s official fan account for her and Travis’ romance, Tayvis Nation, who tweeted, “Kylie singing along to love story??? oh she is such an icon i’m sorry.”

Jason, 36, meanwhile, busted a move when “Scatman” began to play.

The pair were on hand to bartend at the Eagles Autism Foundation in Seal Isle City, NJ. Kylie and Jason signed autographs and the former NFL player met with children with autism.

“These personal interactions, especially with the kids that are on the spectrum, kids that need the support and the assistance, really reinforces what we’re all here for,” he said.

Kylie’s impromptu performance comes just days after she and Jason attended the “Fortnight” singer’s Eras Tour performance in London with the Kansas City Chiefs tight end, 34.

While in the UK, Jason  — who shares daughters Wyatt, 4, Elliotte, 3, and Bennett, 1, with Kylie — met Prince William, Prince George and Princess Charlotte backstage at Wembley Stadium.

“I gotta say, Prince William was fantastic, but the highlight was Princess Charlotte,” Jason said on Wednesday’s “New Heights” episode. “Prince George was great too. She was so f–king adorable.”

He continued, “I cannot express how… I don’t know, maybe it’s because I have three girls now — she had fire to her, she was asking questions. That was the most electric part of the [royal encounter].”

Ironically enough, Jason had insulted the monarchy earlier this month by saying, “f–k kings,” during the brothers’ Father’s Day episode of their podcast.

“Listen, we’re Americans,” he said. “We don’t do royalty.”
