It might not come as a surprise considering his vast media and product empire, but P Diddy is the world's richest rapper and worth $475 million. The hip hop mogul was named top of the Forbes list but warned fans that this didn't mean much: "I think people think that I have that money actually sitting at home in the basement. To everyone calling me for a loan today, I do not have that money today."

Jay-Z came in second in the poll with $450 million, with Dr. Dre in third on $125 million. 50 Cent and Birdman - Cash Money Records co-founder Bryan Williams - tied in fourth place on $100 million each.
