Grammy award winner Justin Bieber has revealed in an Instagram video that he has been diagnosed with Ramsay Hunt syndrome which has caused him to have partial facial paralysis.

Ramsay Hunt syndrome is when a shingles outbreak affects the facial nerve near someone’s ears.

He said: “Hey everyone. Justin here. I wanted to update you guys on what’s been going on,” he said. “Obviously, as you can probably see from my face, I have this syndrome called Ramsay Hunt syndrome and it is from this virus that attacks the nerve in my ear and my facial nerves and has caused my face to have paralysis”

The 28-year-old is currently on his Justice tour in North America and has cancelled performances in Toronto, Washington DC and New York.
