Rihanna is, undoubtedly, the queen of memorable reactions. For every single feeling you need to express, there is a Rihanna GIF perfect for the occasion. With that in mind, it comes as no surprise that her reaction to a fan's singing abilities is one for the books.

Seriously, we have to find a way to put it into all books — even printed ones.

At the Cincinnati stop of her Anti tour, Rih held her microphone out during "FourFiveSeconds." Instead of off-key screaming, as is usually the case with audience participation, she was met with a surprisingly great voice. Rihanna's response? An #ICONIC face and an "oh shit."

Can you imagine eliciting that from Rihanna?

I can.

This would be my reaction.
