Travis Kelce is living his best life in Las Vegas.

The Kansas City Chiefs tight end spent part of his weekend partying in Sin City with his NFL teammates, including quarterback Patrick Mahomes, after arriving in Vegas on Saturday (Feb. 24) following a short visit to Sydney, Australia, where he attended his girlfriend Taylor Swift‘s Eras Tour concert.

Kelce and his teammates hit up XS nightclub at the Wynn Las Vegas, where the Super Bowl champ hung out in the DJ boot alongside chart-topping producer and songwriter Marshmello and was seen belting out classics like Queen’s “We Are the Champions,” Swift’s “Love Story” and Beastie Boys’ “Fight For Your Right.”

Earlier in the day, Kelce and Mahomes attended a brunch event at LAVO at the The Palazzo, according to People. The NFL stars were returning to Sin City following their Super Bowl win against the San Francisco 49ers on Feb. 11.

Just before his Las Vegas trip, Kelce was supporting Swift on the first night of her Eras Tour stint in Sydney. The tight end was one of more than 80,000 people Friday (Feb. 23) at Sydney’s Accor Stadium, where he watched from a VIP tent as his superstar girlfriend commanded the stage. Fan videos captured him exchanging friendship bracelets, passing out guitar picks, interacting with the crowd and dancing along to Swift’s three-hour show alongside Katy Perry, Rita Ora and Baz Luhrmann, who were also guests of honor that night.

Toward the end of her concert, Kelce got a special shout-out from the 14-time Grammy winner. While singing “Karma,” Swift once again changed a lyric to say, “Karma is the guy on the Chiefs,” something she first did when the athlete attended her Buenos Aires show in November.

After the concert wrapped, Kelce waited in the wings for Swift to emerge from backstage, after which she wrapped him in a hug and the couple kissed as lingering fans cheered.

The New Heights podcaster has been with the “Cruel Summer” singer in Australia since Wednesday, when his plane touched down in the land down under. On Thursday, the couple visited the Sydney Zoo, where they were spotted holding hands and taking selfies.

Cameras spotted Kelce getting off a private jet the day before, marking the second time the three-time he has hopped on a plane to go see Swift on her globe-hopping Eras Tour. Swift is playing four dates at Sydney’s Accor Stadium through Monday (Feb. 26), with Sabrina Carpenter as the opener.
