Travis Kelce and Patrick Mahomes led the festivities as the Kansas City Chiefs toasted another AFC West title on Sunday.
“New Year's Eve isn't the only thing we're celebrating tonight!” the reigning Super Bowl champions wrote on social media alongside a selection of photos from inside the Arrowhead locker room.
Kansas City has had a challenging season, losing six games, including five of its previous eight, before Sunday's win over the Bengals.
Kelce also endured some challenges, but after the game he joined girlfriend Taylor Swift to toast the new year.
The 25-17 win over Cincinnati moved the Chiefs to 10-6 – and ensured they would finish the season atop the AFC West.
