For most of us getting front row tickets to a concert is a dream come true but when your favourite star gives you the opportunity to sing along with her and you blow her mind is even better.

This is exactly what happened during Rihanna's  Anti World Tour.

While singing FourFiveSeconds, Rihanna leaned over and passed the mic to Terah Jay who proceed to impress not only Rihanna but the stadium as well.
