It's no secret that Jay-Z has some serious cash flow, but Forbes magazine has confirmed just how much dough he's got to blow. The finance publication just published its annual Hip-Hop Cash Kings list, ranking Jigga man as the top-earning artist of 2010 alongside Sean 'Diddy' Combs, Aliuane 'Akon' Thiam, Dwayne 'Lil Wayne' Carter, Andre 'Dr. Dre' Young and more.

Jay, whose real name is Shawn Carter, ranked at No. 1 with an estimated $63 million earned this year. The mogul upped his earnings thanks to the success of his most recent album, 'The Blueprint 3,' his investment in 40/40 clubs and his stakes in both the Broadway show 'Fela!' and the New Jersey Nets. Additionally, his 'Blueprint 3' tour netted him an estimated $1 million per show, making him this year's biggest baller.

Diddy ranked at No. 2 with $30 million thanks to his investments in Ciroc vodka as well as his Sean John clothing line, Bad Boy Records and appearance in the comedy flick 'Get Him to the Greek.' Akon landed at No. 3 with $21 million (due to Konvict Clothing, a Pepsi endorsement and more), while Lil Wayne dropped behind him with $20 million followed by Dr. Dre at No. 5 with $17 million earned.

Others in the Top 10 include Ludacris, Snoop Dogg, Timbaland, Pharrell Williams and Kanye West, while the Top 20 names Drake, T.I., Swizz Beatz, Eminem as some of hip-hop's financial elite.
