Usually when a star of Rihanna's calibre hands over the mic to concert-goers they're greeted with screams and a slight off-pitch version of their lyrics.
Which is probably why RiRi looked so confused when she pointed the microphone in Teray Jay's direction on her Anti World Tour and he belted out part of FourFiveSeconds.

And it didn't stop there:
After she overcame the initial confusion, RiRi thanked the fan, who seemed pretty damn pleased with himself:
Hundreds of fans at the Anti World Tour have praised the undercover singer in the crowd, including Rihanna's back-up vocalists. Maybe Terah Jay will be joining them some time soon. RiRi could only hope.
In the meantime, enjoy more of Teray Jay's vocals here.
