Mo Money NO Problems For Diddy!

(Reuters) - Rapper Sean "Diddy" Combs topped a list of hip hop's wealthiest artists compiled by Forbes on Wednesday, beating out contemporaries Jay-Z, Dr. Dre, Birdman and 50 Cent.

Combs' net worth was estimated at $550 million, including high returns from his investment in Ciroc vodka as well as clothing lines Sean John and Enyce, record label Bad Boy, marketing company Blue Flame and numerous tech start-ups.
