New Video Shows Jason Kelce Uses Homophobic F-Slur 3 Times in Rage newsthirst.

2:40 PM PT — TMZ has just obtained exclusive video … showing Jason clearly saying “Who is the f***** now?” 3 times to the person who first hurled the slur at him — this after Jason got shoved to the ground by the dude.

12:56 PM PT — More video has emerged from the incident involving Jason Kelce … with the new angle showing the person whose phone Kelce smashed demanding it back.

A scuffle ensues, broken up by people standing near Kelce … before he appears to yell back at the man “Who is the f***** now?” — seemingly referencing the comment that was screamed at him earlier.

We reached out to Kelce and ESPN about this new clip. Kelce’s team has not gotten back to us yet, and ESPN declined to comment.

Jason Kelce lost it at a person in Pennsylvania … grabbing someone’s phone and throwing it to the ground before storming off — right after someone in the crowd called Travis a gay slur.

It didn’t stay positive for long though … ’cause one troll decided to blast Jason’s bro Travis using a slur. You can listen to the video for yourself — it’s an aggressive attack on the tight end and his GF, Taylor Swift.

At this point, Kelce turns around and gets in a person’s face before grabbing the phone and chucking it to the ground. You can’t see the phone after he throws it down … but, the noise it makes when it hits the ground screams “shattered.”

Worth noting … no video has surfaced yet that shows the person who yells the slur — so, it’s unclear if Jason threw the correct person’s phone down. Another angle appeared to show the man yelling at Jason right before Kelce takes his phone and smashes it, but unclear if he also yelled the slur.

Jason usually has pretty genial interactions with fans … but, this one definitely set him off. We’ve reached out to Jason and ESPN, which is the company Jason works for, about the video — so far, no word back.
