Pop superstar Taylor Swift joined in the festivities to celebrate Kansas City Chiefs quarterback Patrick Mahomes’ 29th birthday at his mansion in Kansas City, Missouri, on Sunday night.

The celebration came on the heels of the Chiefs’ narrow victory over the Cincinnati Bengals at Arrowhead Stadium.

Britney Mahomes, wife of Patrick Mahomes, gave fans a glimpse into the lavish celebration by sharing photos on social media. In one post, Swift is seen toasting alongside Britney and other friends, raising glasses of wine to honor Patrick’s special day.

Another photo showed Swift posing in a fun selfie with fellow guests in front of a decorative balloon arch adorned with silver balloons and red LED lights.

Swift’s appearance at the party follows her recent trip to Kansas City to support her boyfriend, Travis Kelce, as the Chiefs took on the Bengals in a thrilling match. Swift was seen celebrating one of the team’s touchdowns with her brother, Austin Swift, during the game, wearing a vintage t-shirt dress and black thigh-high boots.

Inside the Mahomes’ palatial home, guests enjoyed a cookie stand and custom party favors, including plastic cups and thermoses featuring childhood photos of Patrick Mahomes. The party décor also included oversized childhood images of the Chiefs star, giving the event a personal touch.

Swift posed for more fun photos during the party, including one in a photo booth with fellow “WAGs” (wives and girlfriends of NFL players), Shona Weathersby, wife of Chiefs defensive end Chris Jones, and Shariah Gordon, fiancée of Chiefs wide receiver Mecole Hardman. The photos, shared by Weathersby on Instagram, captured the group in playful red cat-eye sunglasses as they made funny faces. “With love,” Weathersby captioned the post, offering fans a glimpse into the lighthearted atmosphere.

The party marks yet another high-profile appearance by Swift in support of Kelce, as their relationship continues to garner widespread attention. Her presence at Patrick Mahomes’ birthday celebration further solidifies her integration into the Kansas City Chiefs’ inner circle of players and their significant others.

As the Chiefs prepare to face the Atlanta Falcons in their upcoming game on Sunday, Swift’s ongoing involvement with the team has fans buzzing about her continued support for Kelce and his teammates.
