Brittany Matthews couldn't be prouder of Patrick Mahomes.
The personal trainer celebrated her fiancé's big win on Instagram Tuesday by sharing a photo of herself smiling with Mahomes, 25, as he cradles her baby bump. "Just so dang proud of you👏🏼 #RUNITBACK," Matthews captioned the post.
On Sunday, the quarterback led the Kansas City Chiefs to victory over the Buffalo Bills, 38-24, securing a spot in Super Bowl LV on Feb. 7, against the Tampa Bay Buccaneers. The Chiefs were last year's Super Bowl champs, and with Mahomes returning from concussion protocol, the team was primed to make it to the big game for a second straight year.
For game day on Sunday, Matthews shared a pair of photos showing herself ready to cheer on her fiancé, writing, "Let's do this." She first announced her pregnancy news in September, shortly after the couple, who began dating in their teens, got engaged.
