Really, Philadelphia? You didn't see this one coming? Over 4th of July weekend, Nicki Minaj , along with other performers, like Ed Sheeran , performed at a 'family friendly,' concert along the Ben Franklin Parkway in Philadelphia. Well, concert-goers got a surprise when Nicki let the curses fly when she performed her single , ' Yass Bish ,' which is full of profanities. The Mayor of Philadelphia, Michael Nutter , was PISSED when he found out because Nicki had allegedly agreed, along with the other performers, to modify her lyrics to be less profane.
