Nicki Minaj is mourning the loss of her tour manager.

De'Von Pickett, 29, was fatally stabbed in Philadelphia in the early hours of Wednesday morning (Feb. 18).

 According to NBC Philadelphia, the stabbing occurred during a bar fight.

The argument began around 2 a.m. inside Che Bar & Grill in Philadelphia's West Oak Lane neighborhood and spread onto the street.
