Justin Bieber announced Friday he’s been diagnosed with Ramsay Hunt syndrome, a rare disorder that’s left part of his face paralyzed.
As a result of the diagnosis, the “What Do You Mean?” singer has postponed the rest of his world tour.
“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, my facial nerves and has caused my face to have paralysis,” the pop star said in a video posted to Instagram. “As you can see, this eye is not blinking. I can’t smile on this side of my face, this nostril will not move. So there’s full paralysis on this side of my face.”

According to the Mayo Clinic, the disorder “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.”
Earlier this week, Bieber postponed three shows because of an undisclosed health issue. In his Friday post, the singer said his condition is “pretty serious.”
“So for those who are frustrated by my cancellations of the next shows, I’m just physically, obviously not capable of doing them. This is pretty serious, as you can see,” he explained. “I wish this wasn’t the case, but obviously, my body’s telling me I gotta slow down and I hope you guys understand.”
He added that he plans to “rest and relax” to get back to 100 percent.
In the caption for the post, the 28-year-old performer asked his followers to “keep me in your prayers.”
