Travis Kelce and Taylor Swift partied into the wee hours of Monday morning after the tight end’s Kansas City Chiefs beat the 49ers in overtime to secure back-to-back Super Bowl titles.

The couple, who’ve been dating since last summer, attended a star-studded bash at XS Nightclub at Wynn Las Vegas, where they were seen kissing and dancing together in the VIP section.

They arrived at the party around 2:15 a.m. with Chiefs quarterback Patrick Mahomes and his wife, Brittany, who was named a 2024 Sports Illustrated Swimsuit rookie last week.

Swift and Kelce were also seen walking through the venue with his big brother, Eagles center Jason Kelce, actress Blake Lively and Swift’s brother, Austin Swift, and his girlfriend, Sydney Ness.

The group enjoyed bottle service, and at one point, Kelce took the mic and held a bottle of Armand de Brignac Ace of Spades Brut Gold Champagne.

Swift and Kelce were also seen dancing together in the DJ booth to her hit song “Love Story.”

The three-time Super Bowl champ and 14-time Grammy winner munched on a special delivery of chicken fingers and fries as they kept the party going until 5:15 a.m.

Mahomes and Brittany celebrated until about 3:30 a.m. before leaving the party.

Model Winnie Harlow and actor Miles Teller, who’s married to Swift’s best friend, Keleigh Teller, were also at the bash.

At one point, Swift was seen wearing Kelce’s custom black Amiri jacket.

They partied the night away after sharing a kiss on the field during the Vince Lombardi Trophy presentation.

Prior to his stop at XS nightclub, Kelce partied at Zouk nightclub, where Ludacris, The Chainsmokers, Post Malone and Quavo performed.

The Chiefs’ Super Bowl 2024 parade is scheduled for Wednesday, Feb. 14, in Kansas City

It’s unclear if Swift will be in attendance as her Eras Tour resumes on Friday in Melbourne, Australia, where she’ll perform three shows from Feb. 16-18.

Kelce is reportedly set to join Swift on the international leg of her Eras Tour this offseason.
