Chiefs quarterback Patrick Mahomes is riding high following his first career playoff win Saturday over the Indianapolis Colts.

Mahomes, who completed 27-of-41 passes for 278 yards in snowy Kansas City, appeared to celebrate the 31-13 victory with girlfriend Brittany Matthews, who shared a photo of the couple cuddling up outside Arrowhead Stadium.

“Just a few East Texas kids that had to grow up a little faster than expected,” Matthews posted on Instagram after the game.

Mahomes, 23, a native of the Lone Star state, attended college at Texas Tech, before being selected by the Chiefs 10th overall in the 2017 draft.

As for Matthews, she continues to be Mahomes’ biggest fan on game days. Following November’s epic thriller between the Rams and the Chiefs in Los Angeles, where Kansas City fell 54-51, the University of Texas at Tyler grad made sure she was there for her beau following the crushing loss.

“Sure missed this guy❤️ #greatgame,” she posted on social media at the time.

Expect Matthews to cheer Mahomes next week, when the Chiefs battle either the Chargers or the Patriots in the AFC Championship.
