They’re shaking off the loss.

Taylor Swift and Travis Kelce celebrated Patrick Mahomes’ 30th birthday Sunday night after the pop superstar stealthily attended her beau’s game on Sunday.

The couple appeared to be in high spirits despite the Kansas City Chiefs losing to the Philadelphia Eagles earlier.

Country singer Kane Brown and his wife, Katelyn Brown, shared a photo of themselves posing alongside Swift, Kelce, Mahomes, and Mahomes’ wife, Brittany Mahomes.

Swift wore a plaid vest and miniskirt set by Simkhai, which she paired with sky-high Gucci platform heels and a Chanel necklace.

In Brown’s second slide, he posted a video of Mahomes clapping and blowing out his birthday cake lit with sparklers.

Brittany happily clapped for her husband as a man singing happy birthday to Patrick could be heard in the background.

The NFL athlete — who was dressed casually in a white shirt, black pants, a black hat and sneakers — celebrated early as his actual birthday is on Sept. 17.

Kane captioned the post, “Happy birthday Pat & congrats TT❤️ thanks for hosting us Britt 🙏🏽.”

The bash was held at Kelce and Mahomes’ 1587 Prime steakhouse in Kansas City., Mo.

Kelce posed for a picture with sports commentator Chandler Parsons in a photo shared by Parsons’ wife, Haylee Parsons, on Instagram.

Kelce flashed a huge smile in the photo while Parsons put his arm around him, definitely in a better mood after he made headlines during Sunday’s game for slamming his helmet on the sidelines in an emotional outburst.

The tight end, 35, was still sporting his Thom Browne shorts suit he wore to the game.

Swift snuck into the Chiefs vs. Eagles game Sunday with an elaborate barrier to hide her.

The pop star taking elaborate measures to not be seen worried some of her fans as she’s previously been willingly photographed at Arrowhead Stadium numerous times to support Kelce without any issues.

This is the second public outing for Swift and Kelce after announcing their engagement on Aug. 26. They made their first appearance as an engaged couple on Aug. 28 at Arrowhead Stadium to watch Kelce’s alma mater, the University of Cincinnati, take on the University of Nebraska, with Swift flashing her massive engagement ring.

The “Style” singer also celebrated Brittany’s 30th birthday last month in Nashville, when she was photographed sitting beside the birthday girl at a restaurant.
