Jordan said that Joshua reacted angrily to his defeat to Oleksandr Usyk as he was so used to having everything his own way that he didn’t know how to deal with it.
The British superstar flew into a bitter rage as he threw two of Usyk’s belts out of the ring before delivering an emotional impassioned speech.
But Bellew has jumped to the defence of his old pal who has not won a fight for over two years now after suffering consecutive back-to-back defeats to Usyk.
Speaking on talkSPORT, he said: “First of all, I just want to put that absolute muppet straight.
“That man hasn’t a clue, all he does is use big words to confuse and contradict himself.
“He’s an absolute clown.
“Let’s just talk about the points that Simon Jordan made.
“The first point that he made was that Carl Froch and George Groves fought in front of 90,000. Well, obviously, you don’t listen to Froch a lot because it was 80,000. So, there’s the first fact you got wrong.
“Anthony Joshua is the first fighter in UK history to take fights to Wembley Stadium and the Millennium Stadium on a regular basis. He took fights to Saudi Arabia for the first time in history, goes to New York and fills Madison Square Garden.
“This boy has genuinely changed how boxing is seen in this country – that’s the first fact I had to get off.
“Let’s just get it straight, judges have no care in the world for DAZN. Judges only care about being paid and scoring fights. That’s the top and bottom of it. So, that’s another fact he got wrong.
“He also misses the fact that when Anthony Joshua first loses that fight and Oleksandr Usyk gets that Ukraine flag and puts it on his back, Anthony Joshua holds half that flag and holds it in the air – this is before the decision came in.
“Tell him to have a look at the video again and see what he’s doing because he’s obviously got that massively wrong. He’s just an absolute prat at times.
“Who are we watching here? Anthony Joshua or Denzel Washington? How could he possibly think that was acting from Anthony Joshua in that press conference?
“The boy is genuinely heartbroken; he’s just lost the biggest fight of his life to date. He believes 100 per cent he’s going to win that fight going in.
“Let’s not forget he’s probably just been punched well in excess of 100 times in the head before he’s had the outburst in the ring and then had the breakdown in the press conference.
“Simon Jordan has no idea what it’s like to get punched in the face, have a mic stuck in your face at a press conference, in the ring, whatever. He has no idea. So, why does he feel the need to get all of these facts off his chest?”
