Justin Bieber announced earlier in the week that he Hailey Bieber of his Justice world tour, much to the disappointment of his fans.
However, it appears as though it was a decision that was taken out of his hands with reports claiming the star's doctors were actually the people to make the final call for the "fragile" singer.
It's thought that the 29-year-old's previous diagnosis of Ramsay Hunt Syndrome left concerned doctors advising the Baby singer to bring his tour to an end prematurely.
The syndrome caused "quite severe loss" of movement in Justin's face last year, with the singer showing the scary effects in a social media video.
Ramsay Hunt syndrome (RHS) is a condition which is caused due to viral reactivation. It is one of 60 causes of facial palsy, or facial paralysis as it is known in the US.
It was suggested last June by a neurological expert that the diagnosis could have long-term issues for the star, but just a month after sharing his condition, Justin was back on the road.
Now, however, Justin has permanently pulled the plug on the tour and insiders say he had no choice.
Speaking to Mail Online, a source said: "Justin is fragile and has been worn thin lately. He was told that this needed to happen and he was left with no other choice.
"'He knows that if he did not cancel the remaining tour dates, it could have a horrible impact on his overall health. If he does not have his health, he has nothing."
The dates he has been forced to cancel would have seen him take to the stage in the UK, Australia, Poland, France, New Zealand, Denmark and the Czech Republic.
The source added that Justin - who is yet to speak publicly about the cancellation - feels "horrible" over needing to upset his fans, but was ordered to do so by doctors and his wife Hailey Bieber.
They continued: "For so many years, Justin felt like he was invincible and that nothing could hurt him. But after getting sick with Ramsay Hunt, it became so clear to him that he is not."
The cancellation comes as wife Hailey gushed over him in a sweet 29th birthday post on social media. Sharing a number of snaps, including a cute throwback of toddler Justin, the model wrote: "29 never looked so good. Happy Birthday to you best friend! Words couldn't possibly sum up all that you embody.
"So here's to more joy, more travel, yummy food, adventures, more peace, fun, and most of all more love."
