Mogul earned $63 million over the last 12 months, according to business magazine.By Jayson Rodriguez Jay-Z Photo: WireImage For the third time in four years, Jay-Z has been crowned the "Hip-Hop Cash King" by Forbes. The Brooklyn lyricist topped the business magazine's annual ranking of high-rolling hip-hop stars by earning $63 million over the past 12 months, thanks to business ventures like a high-grossing tour, real estate investments and the successful Broadway production "Fela!" Jay-Z's income more than doubled the total brought home by 2010 runner-up Diddy, who clocked in at #2 on the list with $30 million earned thanks to endorsement deals and roles in films like "Get Him to the Greek." Akon came in third, earning $21 million from endorsement deals and his signing of Lady Gaga to his Interscope-backed label KonLive. Lil Wayne landed at the #4 spot with $20 million in earnings, most of which came through touring; the rapper's tours last year, "I Am Music" and "America's Most Wanted," were the biggest hip-hop outings of 2009.
