Jason Kelce angrily slammed a fan's phone to the ground after they called his brother Travis a 'f*****' for dating Taylor Swift.
The older Kelce brother and recently retired NFL star was at Penn State on Saturday for the school's huge college football game against Ohio State.
Footage posted to social media shows Kelce walking through a crowd outside the stadium with a crate of beer in his hands.
As fans lined up for selfies and fist bump, an unidentifiable male can be heard shouting: 'Hey Kelce! How does it feel your brother is a f***** for dating Taylor Swift?'
Kelce continues walking momentarily but then turns around, grabs a fan's phone and proceeds to angrily slam it down into the ground. He then picked the phone up and walked away.

Kelce then walked away with the guy's phone before asking him: 'Who's the f***** now?'

But, as he continued to walk off, the male chased Kelce and said 'give me my phone' to which Kelce replied: 'Who's the f***** now?'
It is unclear whether the phone belonged to the male who made the disparaging comment about Kansas City Chiefs star Travis.
The sound of the phone smashing the floor prompted audible jeers from those around him before he continued to walk away.
Kelce's response is indicative of how close the brothers are. Their relationship is at the core of their smash-hit New Heights podcast and Jason regularly supports his younger brother at Chiefs games and major events.
Jason has also been to a number of Swift's Eras Tour shows - both with Travis and his own young family - as they have embraced the popstar ever since her relationship with Travis became public knowledge in 2023.
