Travis Kelce is living it up in Las Vegas!

The Kansas City Chiefs player, 34, was spotted partying with teammates including Patrick Mahomes in Sin City on Saturday, shortly after arriving in Vegas from Sydney, Australia, where he had spent time with his girlfriend Taylor Swift during her Eras Tour shows in the city.

In a video posted on X (formerly Twitter), Kelce hung out in the DJ booth at XS nightclub at the Wynn Las Vegas alongside EDM star Marshmello, who was playing at the nightclub. In another clip posted on the social media site, Kelce and Chiefs teammates sang Queen’s track, “We Are The Champions.”

Earlier, a video posted on X showed the tight end arriving at the venue alongside friends, including Mahomes, 28.

Kelce had also visited LAVO at the Bellagio Las Vegas after arriving in Vegas on Saturday. He joined teammate Mahomes, who was already in town for a bachelor party, with a snap shared on X showing the teammates at a brunch event.

Travis Kelce Returns to U.S. as Taylor Swift Performs 2nd Sydney Eras Tour Concert

Kelce’s return to Vegas — where the Kansas City Chiefs won the Super Bowl on Feb. 11 — comes after his whirlwind trip to Sydney to support girlfriend Swift, 34, on her Eras Tour there. The “Karma” singer concludes her round of shows in the city on Monday.

The couple were spotted spending quality time together at Sydney Zoo shortly after Kelce’s arrival on Thursday. Kelce was next seen in a video posted to X attending Swift’s Friday show at Sydney’s Accor Stadium as he walked through a crowd to his section and waved at fans.

In other footage posted on X, Kelce — who wore friendship bracelets on both arms, exactly like those swapped by Swifties throughout the Eras Tour — clapped and smiled as the music swelled in the stadium. Photos also showed the tight end waving and dancing throughout his girlfriend’s performance.
