After a crazy month, Nicki Minaj is set to hit the stage and will be joining Rihanna, Jessie J and other big names at this year’s Hackney Festival in London later this month. Performing on June 23, The Cash Money diva will be sharing the main stage with Jay-Z and Ed Sheeran. Being part of the London 2012 Festival (the events leading up to this year’s Summer Olympics), the event will be monumental.This news comes a week after Minaj got into some heat with Hot 97 radio DJ Peter Rosenberg, who publicly announced during the Radio Station ‘s SummerJam that Minaj was not “real hip-hop music.” The controversy grew when Funkmaster Flex got involved and thought she was taking Rosenberg’s comments too seriously.
