The Kansas City Chiefs player flew back to the U.S. on Saturday after supporting girlfriend Swift on tour in Sydney, Australia

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, while 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. The players rocked up to the club at around 12.15 a.m. and partied in a VIP area, where as well as bottle service, the 2024 Super Bowl champions had a five-tiered custom football-themed cake and were given championship belts to celebrate their big win. Before leaving the club at around 4.15 a.m. the group were in a celebratory mood, even showering the crowd with champagne.

Ahead of the night at XS, Kelce had also visited LAVO at The Palazzo after arriving in Vegas on Saturday. He joined Mahomes, who was already in town for a bachelor party, and other Chiefs teammates for a champagne brunch that included plenty of champagne, as well as seafood towers and waffle platters.

A snap shared on X showed Kelce and his teammates at the fun brunch, with the tight end sporting a print shirt as he held a beer and a bottle of champagne.

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.

After her performance, Swift and Kelce were spotted sharing a kiss offstage in another adorable video shared on X.

Kelce previously supported Swift in November as he flew out to Buenos Aires, Argentina, to watch her perform in concert. After closing the show, cameras caught Swift running into Kelce’s arms as the pair kissed backstage.

After winning this year’s Super Bowl, Kelce shared his intentions of spending his offseason accompanying girlfriend Swift, an insider told PEOPLE, as they “are making plans for the summer and are excited to travel together in Europe when Taylor takes her tour there.”
