Jason Kelce was filmed Saturday smashing a Penn State student's phone to the floor after a heckler disparaged his brother for dating Taylor Swift.

“Kelce – how does it feel that your brother wants to date Taylor Swift?” A troll could be heard screaming in the background of a video shared on social media.

Immediately afterwards, the former Philadelphia Eagles center turned around and slammed a phone on the ground. The phone appeared to belong to someone standing directly behind him.

Jason then turned back around and walked away with a serious expression on his face.

It is unclear whether the phone he smashed belonged to the person who asked the offensive question.

Campus police told Page Six that no incident report was filed and that they had no further information on the matter.

Page Six has reached out to representatives for Kelce, his brother Travis Kelce and Swift for comment, but we did not receive an immediate response.

Jason, 36, was at Penn State's University Park campus for ESPN's “College GameDay.”

He was also there to take part in Pat Mcafee's “College GameDay” kicking challenge, which encourages students to kick a field goal in Vans and win big cash prizes.

The NFL star-turned-commentator has always been a supporter of his brother's relationship with Swift.

“We just want to support him and their relationship and everything they're doing right now because it's so wonderful right now,” he told reporters at an Eagles Autism Foundation event in June.

He even supported Swift at one of her Eras Tour concerts in London that same month and watched her perform again in Miami in October of this year.

Although he is a big fan of the romance between Taylor, 34, and Travis, 35, he admitted on a radio show in September that the attention the relationship brought him and his family can be “overwhelming.”

“It's a lot. There are a lot of people who are constantly paying attention, which is sometimes positive and negative,” he said candidly.

“But I think that she's built such a huge following and has so many people that really, really love her that it's really cool at the same time,” he added.
