Pregnant Brittany Mahomes kept it chic and cozy for husband Patrick Mahomes' Sunday, December 15, football game.

Brittany, 29, stepped out on the sidelines of the Kansas City Chiefs' latest away game against the Cleveland Browns in a caramel-colored outfit. She paired her beige puffy jacket with fuzzy earmuffs from Prada. Underneath, Brittany wore a black, long-sleeved shirt and coordinating bottoms.

For glam, Brittany wore her signature blonde locks straight down her back.

Through the years, Brittany has been Patrick's No. 1 cheerleader.

"He doesn't get nervous or stressed at all. That's just what he likes to do," Brittany said during an August appearance on the "WHOOP" podcast, noting she gets more anxious about the games. "I think he loves going into a new week having new game plans, having new challenges, having new people that he's playing."

After Sunday's game, Brittany will have more chances to cheer on Patrick during the next Chiefs matchups against the Houston Texans on December 21 and the Pittsburgh Steelers on December 25, respectively.

"As we go into another short week, and then, the one after that, I'll focus on those opponents," Patrick said during a press conference earlier this week. "I'm excited to play on Christmas. But, you never want to play this amount of games in this short amount of time," he added. "It's just not great for your body, but at the end of the day, it's your job. You have to come to work and do it."

Brittany is often joined by the couple's daughter Sterling, 3, and son Bronze, 20 months, during the games.
