Former heavyweight champion Fury claimed Joshua is “just a poor man’s Frank Bruno” as he posted a picture of the ex-WBC title holder on his social media account.
But current IBF king Joshua, who fights Wladmir Klitschko on April 29, responded: “Typical Tyson Fury always talking BS around fight time.
“Same offer as last time. Two ringside tickets, don’t bring a plus one it’s for your fat a**.”
Fury hit back by posting a picture of himself with his world title belts and said: “when you do this come back and talk BS, soppy b*******. You can’t even carry my jock strap flex, you stay humble w*****. KO.”
Bruno, who won the WBC title in 1995 before losing it to Mike Tyson a year later, joined in the debate on Twitter.
He added: “I reckon you boys should just save it for the ring. Let the fists do the talking.”
Fury has not boxed since he beat Klitschko in November 2015.
The Manchester-born fighter was due to face the Ukrainian in a rematch but pulled out of the first date because of an injury before a failed drug test for cocaine ended the chance of the pair meeting again.
Klitschko then turned his attention to facing Fury’s fellow Brit Joshua and was due to face him in December before it got pushed back to April.
They will now clash in front of 90,000 fans at Wembley Stadium in what is set to be the richest fight ever staged in Britain.
