Justin Bieber's journey from YouTube sensation to worldwide superstar In May 2015, singer Justin Bieber attended the Met Gala in New York.

According to the Mayo Clinic, Ramsay Hunt syndrome "occurs when a shingles outbreak affects the facial nerve near one of your ears. 

In addition to the painful shingles rash, Ramsay Hunt syndrome can cause facial paralysis and hearing loss in the affected ear. 

Justin Bieber stated on Friday that he will be taking a hiatus from performing due to facial paralysis on one side. 

The musician stated that he has Ramsay Hunt syndrome, which has left him unable to move half of his face and unable to perform on stage, in a video shared to his verified Instagram account. 

It's because of this virus that affects my ear nerves and facial nerves, paralysing my face," he explained in the video. 

This eye does not blink, as you can see. This nostril will not move, thus I can't grin on this side of my face. So this side of my face is completely paralysed. 

Bieber responded to fans who were disappointed by his previous performance cancellations by saying he's "physically, clearly, not capable of doing them."
