Sometimes life catches you off guard. And sometimes a fan with a serious set of pipes catches you off guard, too.
That's exactly what happened to Rihanna on Saturday night at her Anti World Tour stop in Cincinnati at the U.S. Bank Arena. The singer bent down to share the spotlight with a fan during her performance of "FourFiveSeconds" and got a surprise when he belted out the song like a pro.
The fan was identified as Terah Stewart, an administrator at Ohio State University. Needless to say, Stewart was excited.
Stewart had a feeling it was going to be a good night even before the impromptu duet.
