What a fumble.

Patrick Mahomes explained why he awkwardly turned away Netflix’s football-shaped cake during his post-game interview after leading the Kansas City Chiefs to defeat the Pittsburgh Steelers on Christmas Day.

The quarterback and his teammate Travis Kelce were speaking with an interviewer on Netflix’s livestream of the festive face-off when she urged the NFL players to each open up a football.

“I’d like for you to go ahead, pick ’em up, and they are a little bit heavy, but you can open them up,” the journalist said.

Mahomes, 29, and the tight end, 35, both reached for the special pigskins and pried them open, only to find out they were actually red velvet cakes decorated to look like footballs.

“Oh, yeah! Look at that. A little red velvet,” Kelce cheered before taking a big bite out of the baked good.

Mahomes, however, opted out of tasting the dessert and awkwardly held the pieces in his hand.

“I’m watching my weight for playoffs,” he shared.

Kelce quickly jumped in to cover for his buddy, saying that they would take the cake into the locker room and pose for some photos with the treat.

“Coach Reid’s ready for it. I’ll take it to him,” Mahomes said of Chiefs head coach Andy Reid.

Mahomes didn’t completely snub the streaming service during the encounter, though, as he happily accepted a red and white coat decorated with the NFL logo and candy canes.

Both Mahomes and Kelce rocked the Santa-inspired puffers and returned to their locker rooms still wearing the holiday duds.

Kelce was clearly feeling the Christmas spirit, as he arrived to the game wearing a red Santa hat earlier in the day.

His girlfriend, Taylor Swift, was noticeably a no-show despite attending his Christmas Day showdown last year with her family.

The pop star, also 35, still showed some love for the athlete when she “liked” an Instagram post about Kelce breaking his team’s record for most receiving touchdowns Wednesday.

Meanwhile, Mahomes’ pregnant wife, Brittany Mahomes, watched the game from their home in Kansas City, Mo., with their two kids: Sterling, 3, and Bronze, 2.

Patrick revealed in a Netflix interview this week that Brittany, also 29, is due “any day now.”
