Travis Kelce SLAMS his helmet to the ground and clashes with coach Andy Reid in front of his girlfriend Taylor Swift as Kansas City Chiefs suffer Christmas Day meltdown vs. Raiders

Travis Kelce had a meltdown on Christmas Day in front of his girlfriend Taylor Swift when cameras caught him slamming his helmet into the ground and colliding with his head coach on the sidelines.

Pop superstar Swift flew to Kansas City with her mom and dad on Christmas morning, but Travis was clearly feeling a little “Bah Humbug” during the game against the Las Vegas Raiders.

Shortly after the Chiefs gifted their opponents back-to-back defensive touchdowns in an NFL-record seven seconds, Kelce returned to the sideline and threw his helmet in disgust.

CBS cameras captured the exact moment it happened, when the helmet bounced off the turf and into the Arrowhead stands.

A coach then tried to give Kelce a replacement, but was stopped by head coach Andy Reid, who then chatted with the tight end himself.

In an angry exchange, Reid is seen running into Kelce on a busy sideline before the player then leaves to cool off.

At half-time the Chiefs were booed off the field – and it was a far from merry Christmas for the fervent home support at Arrowhead.

In the stands, Swift watched with both her parents in a Kelce-themed Santa hat, while mom Andrea reportedly attended her first Chiefs game with her daughter.

For Swift herself, a trip to Arrowhead has become the norm in recent months, and she has now attended eight games this season – including trips to Foxborough, New Jersey and Green Bay.

The pair first made headlines when they were spotted together in September, and their whirlwind romance has since taken over the NFL.

It's believed Kelce and Swift will spend the next week together before the Chiefs play again on New Year's Eve.

The pop superstar is currently enjoying some time off before the next leg of her sold-out Eras tour, which heads to Tokyo in early February.
