TYSON FURY has branded Joe Rogan a "bald-headed midget" in an astonishing X-rated rant.
Fury, 34, took to his Instagram story to respond to a prediction made by the controversial podcast host.
Rogan predicted MMA star Jon Jones would be the one to walk out of a room if he and Fury were locked in one together.
However, the Gypsy King did not like the idea of his crown being challenged and took to social media to address the comments, tagging Rogan in his story as well.
He said: "I'm the baddest man on the planet.

"I heard Joe Rogan say something about me, and I’ve been off all the social medias and didn’t reply to that little p****. Little f****** midget, bald-headed midget.
“I heard him say that Jon Jones could f*** me up if we were in the room together. I don’t think so.
Fury then channelled his inner Shakespeare, adding: "Not a man born from a mother could f*** me up, in a room, on our own.
"Whatever happens in that room, I’d be walking out. Not a f****** problem."
Fury could be seen pacing around the gym during the video, perhaps in preparation for his next bout.

But with failed arrangements against Oleksandr Usyk and Andy Ruiz Jr already this year, Fury has now not fought since December - something he blames on the rest of the division.
Following Fury's reply, Jones - who became UFC's heavyweight champion in March after going up a weight division - waded into the debate.
Taking to Twitter he said: "Hey Tyson, it seems like Joe may have struck a nerve.
"I’ll admit there’s no one touching you in that ring right now, but let’s not let that confuse you with what would happen if you stepped foot in my cage.

Jones has won 27 of his 28 UFC bouts, with his one loss coming via disqualification against Matt Hamill after 12-to-6 illegal elbows.
Meanwhile, Fury has 33 wins and one draw from his 34 fights, including 24 KO wins.
UFC commentator Rogan had said: "You want to talk about who’s the baddest man on the planet? If Jon Jones and Tyson Fury are locked into a room, I’m pushing all of my chips on black.
"Tyson Fury is an amazing boxer – he doesn’t have a f***ing chance in hell of making it out of that room.
"He has no chance of making it out of that room. Zero chance. [Fury] would have to catch Jon immediately with one punch, and I just don’t see that happening, man.
"The threat of the takedown looms so large. That shot will come so unexpectedly. When he gets his hands around you, you’ll be so stunned."
