Rihanna who??? All Rihanna does on her tour is grab her crotch (something Madonna did back in the "Express Yourself" era and skip across the stage. Rihanna barely dances. Madonna's last tour broke records. Most grossing tour of all time for a female singer. Rihanna's tour didn't even come close. I love Rihanna but there's no comparison!! She ain't no Queen!! Bu-Bye!
