Teair Tart better be ready to face the wrath of the Swifties.

The Chargers defence lineman smacked Chiefs star tight end Travis Kelce in a shocking scene during an eventful night for Taylor Swift’s fiance during Los Angeles’ 27-21 win in Brazil.

Tart, who did not get ejected for the strike, later posted to his Instagram story the famous “Chappelle’s Show” skit involving Rick James smacking Charlie Murphy with two crying laughing emojis.

The skit famously involves Chapelle saying the catchphrase: “What did the five fingers say to the face? Slap!”

As reported by The New York Post, the shocking scene unfolded in the third quarter with the Chargers leading, 13-6, when Kelce collided with Tart during a block.

Kelce, 35, shoved Tart at the end of the play — which perhaps Tart viewed as late — and Tart countered with an open-hand strike.

The tight end staggered back for a quick second before holding out his arms seemingly in hope of drawing a penalty and a referee quickly tossed a flag.

Kelce then walked right up to Tart and gave him an earful.

The penalty moved the Chiefs up to the Chargers’ 11-yard line and Patrick Mahomes notched a rushing touchdown on the next play to slice the deficit to 13-12.

While striking your opponents can come with an ejection, the referees did not boot Tart from the contest.

Many Americans were in shock that Tart got away without being given his marching orders.

“According to (NFL officiating rules analyst) Walt Anderson, they said because it was an open-hand contact to the head, that was not disqualifying action,” Terry McAulay said on the broadcast.

“On this one, they felt it was just an open hand blow to the head, not a closed fist, not a punch, and they did not disqualify in this case.”

After the upset Chargers win, Tart posted to his Instagram story the skit in which a fictional Rick James — although the story is supposedly true — asked Murphy: “What did the five fingers say to the face?”

James answered, “Slap,” before slapping Eddie Murphy’s late older brother.

Kelce finished with two catches for 47 yards and one touchdown, including a 37-yard grab to slice the Chargers’ lead to 20-18 in the fourth quarter, while Swift did not make the trip.

He also endured a scary moment in the first quarter when he collided with receiver Xavier Worthy, resulting in Worthy exiting the game in a worrisome injury development.

Pop singer Swift’s army of fans went nuts after the game with many raiding the Chargers defence lineman’s Instagram page in support of Swift’s fiance.

“You better apologise for slapping Travis last night that was uncalled for,” an Instagram user that goes by @13longlivetstk87 wrote in the comments of a post from Tart.

“Ur done sweetheart. We do not play about The Killas,” another Instagram user wrote.

“DON’T MESS WITH TRAVIS OKAY BEHAVE YOURSELF AND APOLOGIZE,” an angry Swiftie said.

“hopefully bringing the curse upon your entire bloodline was worth it,” @wildestkris said.
