A furious autograph seeker unleashed an expletive tirade at Jason Kelce as he left ‘Jimmy Kimmel Live!’ Thursday.

The former NFL star, 37, attended an LA studio in the afternoon to film an appearance on the late night show, which aired a few hours later.

As he exited the lot, a man seeking an autograph from the Philadelphia Eagles legend lost it in a berserk rant after Kelce pᴀssed him by.

The supposed fan could be seen hurling explicit insults at the ESPN analyst who was involved in a separate fan altercation earlier in the month.

‘You ain’t nobody special!’ the man hollered in video obtained by TMZ. ‘You’re some s*** bag, f***ing guy that thinks he’s on some pedestal!’

The tirade of expletive insults was so relentless that the retired NFL center had to get back out of his vehicle and attempt to de-escalate the situation.

‘I have a habit of not signing for people that follow where I’m going,’ he explained in the hope of getting the man to back off.

However, the jilted autograph hunter still wasn’t satisfied. Not only did he refuse to let up, he even appeared to challenge Kelce to a fight.

‘I’ll be running the Marvel Cinematic Universe,’ the guy said. ‘Watch for me, you p***y! F*** you. And f*** your love!’

The bombardment of abuse forced Kelce into caving as the former Super Bowl winner eventually headed over to the gaggle of desperate fans and promised to sign their things.

Ever a good sport, Kelce even signed for his ballistic verbal abuser, before shaking his hand.

Kelce’s gesture appeared to appease the furious man with his autograph signing a metaphorical peace treaty and the man ultimately apologizing.

The signature seeker exclaimed that he was ‘ashamed of that moment’ while also demanding that no one post the video of his outburst.

‘You’re good, bro,’ Kelce told him.

Jason Kelce angrily slammed a fan’s phone to the ground after they called Travis a ‘f*****’

Earlier this month, Kelce, who was appearing on ESPN’s College GameDay, smashed a fan’s phone over a remark made about his brother Travis and his girlfriend Taylor Swift.

The older Kelce brother was at Penn State for the school’s huge college football game against Ohio State when he was goaded by a fan.

‘Hey Kelce! How does it feel your brother is a f***** for dating Taylor Swift?’ a fan shouted at him.

Kelce continued walking after the homophobic slur before turning around, grabbing the fan’s phone and furiously slamming it down into the ground. He then picked it back up and said ‘who is the f***** now?’ before walking away.

It is unclear whether the phone belonged to the male who made the disparaging comment about Travis.

Kelce later apologized for the outburst on ESPN’s Monday Night Countdown, he apologized to viewers for ‘falling short’ of his usual levels of ‘common decency and respect’.

‘I think everybody has seen on social media what happened this week,’ Kelce said. ‘Listen, I’m not happy with anything that took place. I’m not proud of it.

‘In a heated moment I chose to greet hate with hate and I just don’t think that’s a productive thing, I really don’t. I don’t think it leads to discourse and it’s the right way to go about things. In that moment I fell down to a level that I shouldn’t have.

Travis and girlfriend Taylor Swift were both proud of Jason for sticking up for them on the day

‘The bottom line is, I try to live my life by the golden rule, that’s what I’ve always been taught; I try to treat people with common decency and respect, and I’m gonna keep doing that moving forward.

‘Even though I fell short this week, I’m gonna do that moving forward and continue to do that.’

The former center’s profile has risen immensely due to his brother Travis’ relationship to pop star Taylor Swift over the past year.

And the couple were both ‘really shocked by this considering Jason is one of the nicest guys in the world,’ a source close to them told DailyMail.com.

‘It really became clear how much he loves and respects Taylor. Travis means the world to him.

‘The use of the word f***** is not okay with him nor anyone. This fan crossed the line. Jason will never stand for anyone insulting his family and he views Taylor as family now.’
