Patrick Mahomes celebrated his 29th birthday early with a bash thrown by his wife, Brittany Mahomes, Sunday night at their swanky Kansas City, Mo., mansion.

Brittany, also 29, shared a behind-the-scenes look at the over-the-top decor, which included an epic balloon arch that welcomed guests into the shindig, on her Instagram Story.

The arch was composed of red and black balloons plus silver mylar balloons in the shape of a chain. A nearby sign read, “Patrick’s 29th.”

Another look at the birthday party shared by Brittany on Sunday night shows a balloon arch surrounding a giant “29” mirror.
Also included in the decor were giant mirrors reading “29” surrounded by the same balloons from the colossal arch. Across from the large “29” sat a pile of silver balls decorated with red LED strip lights.

From there, attendees were greeted by extra large throwback photos of the football star as a child, more balloons, a photo booth and on-theme red uplighting.

Brittany also showed off a custom plastic cup and a beverage koozie with a childhood photo of her husband’s face on them.

The party was scheduled for the perfect time, as the Chiefs came out victorious in a nail-biting game against the Cincinnati Bengals just hours before it kicked off.

Brittany, who celebrated her 29th birthday on Aug. 31 with Patrick, brought their two children, Sterling, 3, and Patrick “Bronze,” 1, to Sunday’s game. She is currently pregnant with their third child.

Taylor Swift also cheered on the Chiefs and her beau, Travis Kelce.

Notably, the pop star, 34, was not seated with Brittany for a second game in a row and instead spent time with Chariah Gordon, the fiancée of Patrick’s and Kelce’s teammate Mecole Hardman Jr.
