On Saturday, during the Kansas City Chiefs' 27-19 win against the Houston Texans, Patrick Mahomes' biggest fan was caught on camera cheering him on from the sidelines.

His biggest fan, of course, is his daughter Sterling, aged three. Brittany Mahomes, Patrick's wife, shared a video story to Instagram of Sterling smiling and clapping during the pregame introductions.

Sterling is wearing hearing protection in the video as BEHA Field at Arrowhead Stadium is known to be one of the NFL's loudest venues.

Brittany also shared another video of her second child, Patrick III, aged two, nicknamed "Bronze," in his mother's arms.

Patrick and Brittany welcomed their first child, Sterling Skye Mahomes, on February 20, 2021. Their son, Patrick "Bronze" Lavon Mahomes III, was born on November 28, 2022.

The couple, who have dated since high school, are expecting their third child. They made the pregnancy announcement in July, later sharing the baby is a girl.

Patrick recently celebrated Bronze's second birthday by releasing a collaboration with Adidas--training shoes called the Mahomes 2 Impact FLX Bronze.

Before Saturday's game against the Texans, Brittany wore an oversized cream coat that received rave reviews on social media.

In Week 17, the Chiefs will be in Pittsburgh to play the Steelers on Christmas.
