When Rihanna was performing in Cincinnati on Saturday, she never expected to be blown away like this.
A fan by the name of Terah Jay was standing in the front row when RiRi began performing her hit "FourFiveSeconds" and urged the pop star to pass him the mic.
Luckily, she saw Jay and motioned for him to come closer to the stage so he could sing into the mic.
Unbeknownst to Rihanna, TJ has been a choir singer his whole life, according to TMZ, and was about to completely rock her world.
