In one new snap, Swift, 34, sweetly wrapped her arm around Kelce, also 34, while clutching a wine glass in her other hand. She leaned in close to her new WAG bestie Brittany, 28, who gripped the pop star’s arm.

Meanwhile, Patrick, also 28, wrapped his arms around his wife’s waist as an unidentified couple smiled beside him.

The Grammy winner shimmered in a silver sequin minidress and wore her blond hair slicked back in a 1920s-style updo.

Her boyfriend sported black sunglasses — despite the party being indoors — and a multicolor corduroy shirt and pants.

Brittany, for her part, sparkled in a strapless black sequin minidress with black sheer tights and rocked a smokey eye and delicate silver hoops. Patrick wore a black-and-white shirt and a baseball cap.

Another photo making the rounds online showed Swift and Kelce posing for a selfie with a group of friends as she held a champagne flute and made a kissy face with her signature red lips.

As Page Six previously reported, the new couple were seen passionately smooching in front of partygoers as the clock struck midnight.

Swift was also seen cheering Kelce on during his Christmas Day game a week prior. The performer, her parents, Andrea and Scott Swift, and her brother, Austin Swift, were seen rolling up to the VIP suite dressed in Yuletide-appropriate attire for the game.

The Swift family was spotted bonding with Travis’ dad, Ed Kelce, in the suite, and Taylor was also seen comforting Brittany after the Chiefs’ loss.
