G-Unit superstar is famously outspoken. While 50 Cent was a flagship star for Interscope Records throughout the early and mid ’00s, last year the Queens, New York emcee moved his G-Unit imprint to EMI Distribution. Although 50 Cent has remained cordial with Eminem and Dr. Dre, the rapper took to Twitter this evening, to reveal tensions with Dre and Interscope’s head, Jimmy Iovine. The root of the conflict reportedly comes by way of 50 Cent launching a headphone line, Sleek By 50 Cent, making himself competition with the popular Beats By Dre line that Iovine and the Aftermath iconic producer famously launched years ago.

Long expected to be including on Dr. Dre’s forthcoming album Detox, 50 Cent then joked that he would lose his role in the highly-anticipated project.

The most shocking news came moments later, when the rapper revealed that he recorded a song, expressing his frustrations with his two former bosses, whom he said “hate me,” despite his feeling “love” for them.
