Los Angeles: One member of Nicki Minaj's touring crew was killed and another seriously injured following an altercation in Philadelphia, where rehearsals for the rapper's upcoming trek were underway.

De'Von Pickett, a roadie, was killed after an argument broke out at Philadelphia's Che Bar & Grill on early Wednesday morning.

Eric Parker, another man involved with Minaj's rehearsals, survived multiple stab wounds to his side in the incident and was taken to an area hospital in critical condition.

"Two members of my team were stabbed last night in Philly. One was killed. They had only been there for two days rehearsing for the tour," Minaj, 32, posted on Twitter.

The 'Anaconda' hitmaker posted a photo of the two victims on Instagram, writing, "Unbelievable. Eric (on the right) is recovering. Another senseless act of violence that took the life of a great guy. So sad."
