The pop star and the football player attended model Karen Elson’s nuptials to Electric Lady Studios owner Lee Foster on Saturday, Sept. 7

Move over, Danny and Sandy — Taylor Swift and Travis Kelce have entered the chat.

On Saturday, Sept. 7, the 14-time Grammy winner and the Kansas City Chiefs tight end, both 34, stepped out in style in New York City. According to Vogue, the pair were attending model Karen Elson’s wedding to Electric Lady Studios owner Lee Foster.

Swift and Kelce’s wedding-guest outfits gave off Grease vibes, as the A-list couple seemingly channeled Danny’s greaser look and Sandy’s dreamy flair following their summer nights together.

Swift wore a Zimmermann Halliday Scallop Midi Dress with cutouts on the side and a romantic corset design on the back. The cream-colored, floral-print dress matched her strappy heels, and she finished the ensemble with her signature red lip.

Kelce looked sleek in an all-black ensemble and wore his hair slicked back. He accessorized with a gold watch and a chain.

The pair’s Saturday night outing comes after the Kansas City Chiefs defeated the Baltimore Ravens in the NFL season opener on Thursday, Sept. 5. Swift was at Arrowhead Stadium in Kansas City, Mo., to cheer on Kelce, wearing a chic denim ensemble paired with red thigh-high boots.

That evening, the couple left the game together in a getaway golf cart and celebrated the Chiefs’ 27-20 win at Prime Social. An insider told PEOPLE of the afterparty, “Everyone partied hard. A good time was definitely had,” and added: “Travis and Taylor both let loose.”

The next day, Swift and Kelce flew from Kansas City to New York and grabbed dinner at Lucali in Brooklyn. A source told PEOPLE about their upbeat date night at the pizza hotspot.“They were sitting in the main room with everyone,” the insider said. “Travis was super nice and thanking everyone around him. Taylor looked stunning, and they seemed very happy together.”

Speculation about Swift and Kelce dating began almost a year ago when the “So High School” singer showed up at one of the NFL star’s games to cheer him on in September 2023. Weeks later, they appeared on Saturday Night Live, surprising audience members and fans alike — and were photographed holding hands outside of the show’s afterparty, cementing their relationship status.

Swift became a fixture throughout the football season, leading to the Super Bowl, which the Chiefs won.

Kelce, meanwhile, supported Swift during her record-breaking Eras Tour during the NFL off-season, attending several international concerts and even appearing onstage during one of her shows at London’s Wembley Stadium in June.
