Justin Bieber reveals rare disorder behind facial paralysis

Los Angeles: Justin Bieber says a rare disorder that paralysed half of the superstar performer's face is the reason behind his tour postponement. The multi-Grammy winner is suffering from Ramsay Hunt syndrome, he said in video he posted Friday on Instagram. The syndrome causes facial paralysis and affects nerves in the face through a shingles outbreak. Bieber's post comes after he cancelled his shows in Toronto and Washington, DC. The singer demonstrated in the video that he could barely move one side of his face, calling the ailment "pretty serious." "For those frustrated by my cancellations of the next shows, I'm just physically, obviously not capable of doing them," he said.
