Jake Paul called a reporter a 'dumbass' following his question during the pre-fight press conference with Mike Tyson.
Paul and Tyson fielded questions from the media in Wednesday's presser ahead of Friday's professional fight.
Tony Bellew hilariously crashed the event as he interrupted a reporter's question to deliver a stunt involving an older gentleman.
Tyson went off on a reporter after being asked what he would lose if he fails to beat Paul.

And Paul pulled no punches himself when he was given a spiky question.
A reporter asked the 27-year-old: "When can we expect you to start fighting legitimate contending fighters in your weight class?"
'The Problem Child', who has recorded 10 victories in his boxing career since turning pro, ruthlessly replied: "I think you're the same dumbass from the other venue."
He added: "Disrespecting Mike Tyson to his face once again. Do you not think that he's a serious boxer?"
After the reporter walked away from the mic, the boxing star said: "He walks away."
Paul has faced intense criticism for the choice of opponents in his career.
He's mainly feasted on former UFC fighters, having lost to the only legitimate boxer (Tommy Fury) on his record.
On his critics, he exclaimed: "I'm blessed to be in the position I am, to be highly criticised. That just means I'm doing something right. No one has had a boxing career like mine. It'll be studied and judged, but I've risen to the top in four years because I've taken risks.
"I was the underdog all the way up until Nate Robinson and that's something that people don't remember [and] don't give any credit to, but I put it on the line against some of the best in the sport every single time.
"That's why I'm here on Netflix against the biggest name in boxing right now."
