Dee's death was confirmed on Twitter by the band's manager Louis Gregory on Thursday. The songwriter would have been 53 on Friday. No cause of death has been released.

"Forever in my Heart. Prince Markie Dee was more than a rapper; he was one of my very best and closest friends," Gregory wrote.

"My heart breaks today because I lost a brother," he added. "I'll always love you Mark and I'll cherish everything you taught me. Tomorrow is your birthday, swing my way big bro."

In addition to Dee (né Mark Anthony Morales), The Fat Boys was made up of Darren Robinson, aka the Human Beatbox, and Damon Wimbley, aka Kool Rock Ski. Robinson died in 1995.
