Mary is gonna mop the floor with Rihanna's bad wig. Rihanna's fanbase are a bunch of effeminate gay boys and fat girls born after 1996, who don't know shit else about music other than downloading fluffy pop crap from iTunes with their mommy's debit cards. MJB's fan base are grown ass men and women, who actually go to record stores and buy whole CDs. That non-singing goat doesn't stand a chance in hell of beating Mary in a first week showdown.
