WATCH: Eagles' Jason Kelce Parties with Bills Mafia Ahead of Brother's Matchup - Hanging Out with the Wrong Fans

Ahead of the Chiefs-Bills playoff game, Chiefs TE Travis Kelce's bother, Eagles guard Jason Kelce was seen partying with fans. However, these were not Chiefs fans, but rather, "Bills Mafia:"

Kelce is known for his party-like behaviour, but usually he parties with his own team, or at least his brothers team. But, in this case, he is partying with the enemies.

Though Kelce was seen hanging out with Bills fans, he still made sure to show love to the Chiefs and his brother during the game, as he was ultimately there to cheer them on:
