Sean 'Diddy' Combs has been named 2014's Wealthiest Hip Hop Artist. Editors at Forbes.com estimate the mogul is worth $700 million (£437.5 million) - $120 million (£75 million) more from last year (13).

Coming in second on Forbes.com's rich list is Dr. Dre with $550 million (£343.8 million), while Jay Z takes the third spot with an estimated $520 million (£325 million) worth.
