Justin Bieber gets honest about his recent health issues, opening up for the first time about being struck by a rare virus that has left half of his face paralyzed — and made him pause his World Tour.

The 28-year-old pop star took to Instagram to share a three-minute video explaining the diagnosis, a complication of shingles that can lead to facial paralysis.

Justin, who has been battling Lyme disease, explained he wanted to update his fans on "what's been going on" with his health recently.

The pop star pointed out that people can "probably see from [his] face" that something isn't normal.

As he began the video, Justin's right eye struggled to blink, and the right side of his face couldn't move.

Starting, he explained:

"Hey everyone Justin here, I wanted to update you guys on what's been going on."

"Obviously, as you can probably see with my face. I have this syndrome called Ramsay Hunt syndrome, and it is from this virus that attacks the nerves in my ear and my facial nerves and has caused my face to have paralysis."

Justin later updated his fans in a sad post.

Justin Had To Postpone His Tour

A few days later, Justin updated his fans, announcing that he was postponing the "next few shows" of his seven-leg, 130-date Justice World Tour due "non-COVID related illness."

The Anyone singer, who boasts 539.2M social media followers, wrote:

The Grammy winner also addressed fans who may be "frustrated" because of his cancelations, writing:

"So there is full paralysis on this side of my face. 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…"

"I wish this wasn't the case, but obviously my body is telling me that I've got to slow down, and I hope you guys understand."

"I will be using this time to rest and relax and get back to 100 percent so that I can do what I was born to do."

Justin concluded by saying he was doing all he can to address the issue, although he didn't know how long it'll take him to recover.

He said:

"I love you guys. Thank you for being patient with me, and I am going to get better."

"I'm doing all of these facial exercises to get my face back to normal and it will go back to normal."

"It's just time, we don't know how much time it will be, but it's going to be okay."

"I hope, and I trust God, and I trust that this is all for a reason. I'm not sure what that is right now, but in the meantime, I'm going to rest, and I love you guys. Peace."

According to the Mayo Clinic, Ramsay Hunt syndrome causes temporary hearing loss and facial paralysis.

The virus becomes reactivated after laying dormant for years and causes inflammation and irritation on the facial nerves.

If antiviral treatment is given within 72 hours of developing symptoms, the patient can get virtually full recovery. But if damage to the nerve is mild, recovery should occur within a few weeks.

This Hasn't Been A Great Year For Justin's Family

Justin's health scare came just three months after his wife, Hailey Bieber (née Baldwin), was sent to hospital following a blood clot in her brain.

At the time of Hailey's ordeal, a source reported:

"Justin is probably more traumatized than even she is."

"When it happened, there was a lot of panic. Justin was crying because you don't expect your young wife to have symptoms that resemble a stroke."

"Justin texted everyone he knew and asked everyone to pray for her, and he never left her side."

The source added:

"Hailey doesn't want anyone to worry about her, but it was a terrifying situation for both of them. Justin is still very worried. He can barely sleep. He stays up watching her while she rests."

"[Justin] would've done anything to help her. It was a moment for them both to be reminded about mortality and focus on what really matters."

Just weeks before Hailey's sickness, Justin had recently recovered from COVID.
