Rapper 50 Cent criticized Nelly for spending too much money on diamond jewelleries and is afraid this addiction will get out of control.

50 Cent, 30, called Nelly a "fool" for spending his hard-worked money on such nonsense things and urged his advisors and friends to talk and guide him on the right direction.

50 Cent says: "I've never seen a chain with ice that big and that clean. Not to say Nelly doesn't have the dough to do it, but I would hope the people around him are smart enough to tell him not to.

"If you gon' spend $5m on diamonds, you's a damn fool."

50 Cent is arguably the most popular gangsta rapper in the world and is currently signed to Eminem's record label Shady Records and Dr. Dre's Aftermath Entertainment.

He burst into widespread prominence with the heavily played song and video ("Wanksta"), featured on the soundtrack for the Eminem film, 8 Mile.
Beyond his mainstream success, he has appeared on almost every major mix tape sold in New York over the past few years.

He won six times Platinum in US and two times Platinum in UK for his album "Get Rich Or Die Tryin'" and sold 11 million copies worldwide.
