Prince Markie Dee, a member of the pioneering hip-hop group the Fat Boys, died aged 52 on Thursday, a day before his birthday, Rolling Stone reports. Together with Human Beatbox and Kool Rock Ski he launched Fat Boys in 1983, becoming one of rap’s premier pop culture ambassadors. The Roots' Questlove said “they were figuratively (no weight jokes) the biggest act in hip hop at some point in time. Like the first act that showed this culture might have some real international legs to it". After the band's breakup, he wrote and produced pop songs for the likes of Mary J. Blige and Mariah Carey under his birth name Mark Morales.
