Jason Kelce shockingly confronted a foul-mouthed autograph hunter after appearing on Jimmy Kimmel Live.
The former NFL star was seen leaving a television studio in Los Angeles on Thursday evening.
Now horrific footage has emerged of the moment he was abused by a fan on his way home.
Kelce, 37, was seen riding in the back of a car surrounded by security when a man, apparently looking over a wall, unleashed a strange gesture at the former Philadelphia Eagles center.
In the clip shared by TMZ, the angry fan raged: “You're not special. You're a vile person, a vile man who thinks he's on some pedestal.”
He continued his X-rated outburst, claiming he's unhappy with Kelsey's “situation” where there's “death on these damn streets two blocks away and you're being exposed.”
The autograph chaser also appeared to threaten him, adding: “I'll pick you up anytime.
“I'm going to run the Marvel Cinematic Universe. Watch me, you bastard. Damn you and your love.”
Kelce eventually made his way to the fans and made it clear that he wanted to sign anything to people “that follow him.”
But in an attempt to calm the situation, he changed his mind and was then heard replying: “I will sign.”
The offending fan then changed his tune and revealed that he was “ashamed of that moment.”
He demanded that the video not be published online, claiming that it was about “love.”
An unhappy-looking Kelce then shook his hand while the fan issued a humiliating apology.
This isn't the Super Bowl winner's first tussle with a fan after he previously attacked a man who insulted his brother Travis and Taylor Swift.
Jason smashed his phone and said, “Who's the fucker now?”
