Corporate sponsors like Coke should think again before hiring this potty mouthed anti-American hack singer for anything.Rihanna performed  American Oxygen  live for the first time at Saturday s March Madness Music Festival.If, by chance, corporate sponsors, broadcasters and the NCAA advised acts playing the March Madness Music Festival to not comment on the controversy that s gripped Indiana, Rihanna and supporting act Bleachers didn t heed that memo on Saturday.Rihanna paused during her performance to verbally slam RFRA in two expletive-laden sentences.The 2015 installment of the annual three-day event was held in Indianapolis, timed to the NCAA s Final Four competition. Rihanna was the headliner of the Coke Zero Countdown concert at White River State Park.Rihanna sang  American Oxygen . It s a sluggish number that frames itself as a 21st-century  The Times They Are A-Changin .   We are the new America,  sang Rihanna in a performance that TBS picked up for broadcast during Saturday s basketball coverage.Rihanna wrote on Twitter afterward,  Thank you Indiana!!!! I would never forget how much fun I had with you tonight!! You blew me away!!! Thank you man!! One love always.  And even though  American Oxygen  hasn t been officially released, the crowd responded to the performance quite strongly.  You SANG EVERY F*CKING WORD!!!!  tweeted Rihanna.  That sh*t legit give me goosebumps!! GAG! WHAT IS NEW AMERICA? IS IT THE HATE AND DIVISION PROMOTED BY OUR PRESIDENT? IS IT THE TURMOIL AND CHAOS IN THE MIDDLE EAST CAUSED BY OUR PRESIDENT? IS IT THE SOARING NATIONAL DEBT IGNORED BY OUR PRESIDENT? IS IT THE COLONIZATION VIA INVASION OF ILLEGALS FROM CENTRAL AMERICA THAT S THE  NEW AMERICA ?Via: indystar
