Jay Z has parted ways with his longtime business partner John Meneilly, reports the New York Daily News. It's unclear what prompted the split and how it was received, though. One source believes the decision was "amicable and mutual," while another insider claims Meneilly didn't want to leave, saying "it wasn't his choice."

A former Provident Financial executive, John Meneilly has been by Hov's side for more than a decade. He was instrumental in establishing the Rocawear clothing brand, as well as striking Jay's unprecedented deal with Samsung last year that guaranteed a million sales of 'Magna Carta... Holy Grail.'

Meneilly has also been a key player in the evolution of Roc Nation, which has grown from a record label to an artist management service and sports agency which boasts stars like Rihanna, J. Cole and Robinson Cano on its roster.
