The Kansas City Chiefs vs. New England Patriots reunited the couple, who PEOPLE reported was unable to celebrate Swift’s 34th birthday together on Wednesday, due to Kelce’s mandatory practice schedule in Kansas City, Missouri.

The pair was said to have celebrated the Midnights artist’s birthday early on Sunday at a holiday party with friends in Kansas City, following the Chiefs’ game against the Buffalo Bills. At the event, the singer-songwriter and the two-time Super Bowl champion were spotted posing with partygoers and exchanging kisses in photos throughout the night.

On her birthday this past week, the “Karma” singer was surrounded by friends in New York City. After enjoying dinner at Freemans and blowing out the candles on her birthday cake from Milk Bar at the Manhattan restaurant’s upstairs bar Banzarbar, the group reportedly took their festivities to the nightclub The Box.

Every Time Taylor Swift Went to a Kansas City Chiefs Game — and Whether or Not the Team Won

Famous friends including Gigi Hadid, Blake Lively, Jack Antonoff, Sabrina Carpenter, Gracie Abrams, Este Haim, Alana Haim, Zoë Kravitz and Antoni Porowski, among others, stepped out to wish the hitmaker a happy birthday, as well as her longtime childhood friend Abigail Anderson — all of whom she shared photos of on Instagram.

The pop star and the football player appeared to be in good spirits when their schedules allowed them to last link up at the Chiefs vs. Buffalo Bills game at Arrowhead Stadium and the holiday party that followed on Dec. 10.

The 1989 artist was photographed spending a portion of the sporting event seated next to the tight end’s mother, Donna Kelce.

Based on posts on social media, it appeared as though Swift also spent the afternoon with Kelce before he hit the field, as well.

Every Photo We Have of Taylor Swift and Travis Kelce So Far

On Monday, NFL barber Patrick Regan shared an Instagram carousel of photos and videos taken before the game and credited Swift for one of the shots.

“Thanks @taylorswift for the Pics of the Gameday Freshy for @killatrav 🙌🏼❤️,” Regan wrote in the caption, giving her credit for the first photo of the post, which showed him trimming Kelce’s hair in his house.

In the same post, Regan also shared a sweet shot of the couple posing together, with the “Lavender Haze” singer planting a kiss on the football player’s cheek while he smiled at the camera.

After Kelce traveled in November to Argentina for the Eras Tour — where the singer changed the lyrics to her song “Karma” to reference him — a source told PEOPLE that their relationship “feels very special.”

“He is a gentleman,” the source shared of the Chiefs player. “He is very focused on his career. He has a great relationship with his family. He has an amazing energy and approach to life.”
