Jason Kelce took part in a few fun festivities alongside the ESPN “College GameDay” crew on Saturday.

But things took an ugly turn after a homophobic comment from a fan outside Beaver Stadium was used in reference to his brother Travis.

The retired Eagles center was seen walking around University Park, Pennsylvania, carrying a case of beer as screams and cheers could be heard around him of people recognizing the former NFL star.

But one comment stuck out from all the noise after one fan made a derogatory comment about Travis Kelce’s high-profile relationship with Taylor Swift.

Kelce quickly turned around to find the person who uttered the insulting comment, putting his hand up in disbelief.

Upon realizing who it was, Kelce grabbed the fan’s phone and slammed it on the ground in anger.

A few gasps could be heard from the crowd around Kelce, who turned and stormed off.

Another angle of the incident showed the fan who first yelled at Kelce, demanding to get the phone back.

Kelce, in the video acquired by TMZ, said to the fan: “Who’s the f—- now?”

Kelce has not yet responded on social media about the incident.

Earlier in the morning, Kelce appeared on the “GameDay” set with Pat McAfee to attempt a field goal challenge that’s become a fun weekly part of the show.
