Travis Kelce and Olivia Dunne trade sports as NFL icon attempts gymnastics tricks

NFL star Travis Kelce and LSU gymnast Livvie Dunne teamed up in an advert for sponsor, Accelerator, with the Kansas City Chiefs tight end attempting some acrobatic tricks.

Dunne, 21, attempted to teach the 34-year-old football star how to stick a landing. The gymnast made sure to tell Kelce to stick his arms out on impact, then put his arms up to signal the end of the routine, before letting out a scream.

Kelce 's attempt impressed Dunne, who gave Taylor Swift's boyfriend a perfect ten rating for his efforts. It was then Dunne's turn to impress the three-time Super Bowl winner with her football skills. Dunne, who's dating MLB hotshot Paul Skenes, was taught the proper way to catch a football by Kelce.

The technique is known as the diamond. Dunne was then thrown a ball from Kelce, who was stood off-camera. Kelce said: "She's Open!"

To Kelce's delight, Dunne caught the football, spiked it, and celebrated. Kelce's collaboration with Accelerator comes as no surprise, with the brand a sponsor of his hit podcast, "New Heights", where he stars alongside his older brother Jason Kelce. In one of the most recent popular episodes, the Kelce brothers enjoyed a trip to London.

Travis Kelce joined his girlfriend, Swift, on stage at Wembley , much to the delight of tens of thousands of Swifties. The A-list couple also got up close and personal with British Royalty, meeting Prince William, Prince George, and Princess Charlotte backstage.

“They were an absolute delight to meet. Wasn’t sure if I was supposed to, like, bow to them, curtsy, just be an American idiot and shake their hand,” Travis said. “We wanted to be polite, especially on this side of the pond.”

“I gotta say, Prince William was fantastic, but the highlight was Princess Charlotte. Prince George was great too. She was so ------- adorable. Like, I cannot,” Jason said.

It was also Jason Kelce's first Swift concert and was left impressed by his younger brother's girlfriend. Jason continued: “It was insanely impressive. There’s something, like obviously Taylor’s an amazing singer-songwriter, but then to be able to go out there and be a performer at that level for how long she was up there for, like, three and a half hours, four hours?”

Swift's acoustic set was the highlight. “It’s just her, a guitar, and 90,000 people,” Jason said. “And she’s blending from one song to another. Like, to be good in front of 90,000 people with just that, I think you have to be amazing. And you have to, one, have great songs and great lyrics, which she obviously has written and made. And then two, be able to perform those seamlessly on the spot, nothing else to hide it, just that was the highlight of the evening for me.”
