Rapper 50 Cent has blasted his former Boxing client Billy Dib for accusing him of owing money.

The Australian professional was one of the first athletes the hip-hop star signed when he launched a boxing promotions company with Floyd Mayweather, Jr. in 2012, and Dib told the Sydney Daily Telegraph this week the deal “was possibly the worst career move that I’ve made in my life” because 50 Cent, real name Curtis Jackson, “basically knew nothing about the sport of boxing.”

He also claims he has only received a fraction of what he was owed by Jackson, which the rapper disputed in a lengthy rant on Instagram.com as he ridiculed Dib’s boxing skills by bringing up his humiliating defeat against Russian fighter Evgeny Gradovich in 2013.

Jackson writes, “The truth is Billy Dib is an ungrateful fighter who was deemed unwatchable by premium networks like Showtime and HBO when I met him. Floyd was mad at me for signing him in the first place. With a record of 35-1 (21 KOs), Dib must have fought 21 cab drivers in Australia because Evgeny Gradovich with a record of 15-0 (8 KOs) beat the s**t out of him, despite taking the fight on a month’s notice.

“It’s no secret that the level of competition and talent, fighting in America is the highest. The best fighters in the world come here to fight… He got knocked the f**k out. I can only set the fight up…I can’t fight for you, punk! I didn’t take a dime of your money. They call me a lot of s**t, but never a thief.”
Officials at the rapper’s boxing firm SMS Promotions filed for bankruptcy in May, two months before 50 Cent filed for bankruptcy protection in July.
Three other boxing clients have issued legal paperwork against the company to get out of their contracts.
