Ferdinand, now a TV pundit, has announced a controversial move into the fight game, but his foray into the sport will only be a one-off.
The 38-year-old is being trained by former super middleweight world champion Richie Woodhall, however there is no scheduled date for his pro debut yet.
But Bellew, who will return to the ring in December in a hugely anticipated rematch with David Haye, believes Ferdinand is purely seeking attention.
The Bomber blasted: “He’s making a mockery of our sport, this sport is not a game, it’s a serious sport and can be very dangerous.
“This is attention seeking of the highest order, I understand that he might have frustrations that he wants to get out. But I believe he could do that in the gym, why does he need to go in a boxing ring?
“He’s a healthy man with a beautiful family and I have huge respect for him after watching the documentary on his family but this stinks of desperation and not being able to let go out of the spotlight.”
The Scouser’s outburst came after he revealed that he received a surprise early morning wake-up call from the drug testers – after calling for life bans for all drug cheats.
