Last but not least, 50 Cent landed fifth on the Forbes list, with $125 million. Curtis “5o Cent” Jackson earns his bread in music, merchandise, acting, gaming — and books, believe it or not. Ever since his debut in Get Rich or Die Tryin’, 50 Cent has been at the top of his game running his record label G-Unit, launching artists like Lloyd Banks and Kidd Kidd. 50 Cent has also been hard at work pursuing new ventures like getting his own headphones brand like fellow rapper Dr. Dre, this one called SMS Audio, and his own energy drink, SK Energy. The rapper is also busy on his next album, Street King Immortal, to be released this spring.
