Keri Hilson is one tough critic. The “Pretty Girl Rock” singer was asked by Funkmaster Flex to rate some of hip-hop and R&B’s leading men and she didn’t let the fellas off easy. Trey Songz, Usher, Drake, J. Cole, Kanye West, Lil Wayne, John Legend, and more all went under Miss Keri’s microscope. Her “Knock You Down” collaborator Kanye scored a 9/10 for his creativity, while J. Cole and 50 Cent didn’t fare so well. Sorry Weezy, but having numerous kids doesn’t make you a 10 in Keri’s eyes. Find out what turns her on below.
