Travis Kelce and Patrick Mahomes sing “We Are the Champions” while partying in Vegas until 4 a.m

Travis Kelce parties in style.

Just hours after landing in Las Vegas following a whirlwind two-day trip to Australia with girlfriend Taylor Swift, the Kansas City Chiefs star partied until the wee hours of the morning at XS Nightclub.

He joined the 2024 Super Bowl champion quarterback Patrick Mahomes and more than 20 teammates at the Sin City hotspot on Saturday night.

The NFL players celebrated their victory over the San Francisco 49ers from the club’s VIP area, where they were joined by Wynn Nightlife’s resident DJ Marshmello and sprayed champagne into the crowd.

At one point, they jumped on stage to sing some hits, including Queen’s cla*sic “We Are the Champions” and Swift’s 2008 song “Love Story.”

The group – who celebrated with customs bosses – decorated money raining from the ceiling, red and yellow confetti and a five-tier football-shaped cake – didn’t call it a night until after 4 a.m.

Earlier in the day, Kelce and Mahomes held a brunch at LAVO, where they sipped champagne at a VIP table surrounded by women.

Photos from the daytime party show the tight end, 34, wearing a yellow Hawaiian-style shirt — which he wore for the rest of the night — as he stood on top of the table and danced.

The last time Kelsey hit the Las Vegas strip was with the “Cruel Summer” singer after he notched his third Super Bowl win earlier this month.

Swift, 34, was on hand to celebrate with her beau at the team’s star-studded bash, which was also held at XS nightclub.

Shortly after the celebration, she flew to Australia to continue her successful Eras Tour.

Kelce then followed suit by flying Down Under for a few days to support Swift at her first show in Sydney.

The athlete was seen entering the Accor Stadium on Friday night, waving five fingers high while shaking several friendship bracelets on his wrist.

He took part in the show from the VIP tent alongside celebrities like Rita Ora and Swift’s ex-girlfriend Katy Perry, who poked fun at their past feud during a performance of “Bad Blood.”

The next day, Page Six confirmed that Kelce was indeed returning stateside to reunite with his teammates as they continued to celebrate their 2024 Super Bowl victory.

For her part, Swift remained in Sydney to attend the last two shows of her Australian Eras tour, before continuing the international leg of the tour in Singapore.
