Justin Bieber has revealed that he has been diagnosed with Lyme disease.

The 25-year-old singer took to Instagram Wednesday, denying rumors made about to his recent appearance.

While a lot of people kept saying justin Bieber looks like shit, on meth etc. they failed to realize I’ve been recently diagnosed with Lyme disease, not only that but had a serious case of chronic mono which affected my, skin, brain function, energy, and overall health,” he wrote.

The American Lyme Disease Foundation describes Lyme disease as being caused primarily by deer ticks, transmitting the bacteria to any human or animal it bites. It manifests itself as a multisystem inflammatory disease that affects the skin in its early, localized stage, and spreads to the joints, nervous system and, to a lesser extent, other organ systems in its later, disseminated stages. It is curable if detected in its early stages.

Additionally, according to the Centers for Disease Control and Prevention, over 300,000 Americans become diagnosed with Lyme disease every year.

Bieber confirmed that more information on his diagnosis will be revealed in his upcoming YouTube docuseries, Justin Bieber: Seasons.

These things will be explained further in a docu series I’m putting on YouTube shortly.. you can learn all that I’ve been battling and OVERCOMING!! It’s been a rough couple years but getting the right treatment that will help treat this so far incurable disease and I will be back and better than ever NO CAP.

Following his reveal, Bieber’s wife, Hailey, went on Twitter to shut down trolls who were criticizing her husband’s announcement.

Aftewards, she thanked Yolanda, Gigi and Bella Hadid for bringing her “so much clarity and information on Lyme disease” and answering her questions.

She also sent love to Avril Lavigne, another celebrity fighting Lyme disease.

Last week, Bieber released his newest song, “Yummy,” which is his first solo single in four years.
