Last night, Justin Bieber took to Instagram to make a shocking announcement — he has spent the last few years battling Lyme disease. In his post, Bieber spoke of dealing with internet trolls that have slammed him for looking “like shit” without knowing the reason why.

“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,” Bieber wrote. “It’s been a rough couple years but I’m getting the right treatment that will help treat this so far incurable disease, and I will be back and better than ever NO CAP.”

Check out his post in full below.

Following the reveal, Hailey Bieber asked fans to educate themselves on Lyme disease. “Please do your research and listen to the stories of people who have suffered with it for years,” she said on Twitter. “Making fun of and belittling a disease you don’t understand is never the way, all it takes is educating yourself.”

Singer Avril Lavigne, who has battled with Lyme disease herself, also took to social media to show her support. “To everyone affected by Lyme, I want to tell you that there is HOPE. Because Lyme is a daily struggle, for the better part of two years, I was really sick and fighting for my life.”

Today @JustinBieber shared that he has Lyme disease. There are too many people that have this debilitating disease! People I love and care about and many friends and fans I have crossed paths with. To everyone affected by Lyme, I want to tell you that there is HOPE. Because Lyme is a daily struggle, for the better part of two years, I was really sick and fighting for my life. Writing #HeadAboveWater helped me get through the worst of it, but the bad days still come and go. At the time, putting together my album saved my life. I needed to tell my story and to be able to share my experiences with others. Lyme disease is in all 50 states in the US and in EVERY country in the world, except Antarctica. It is a global pandemic but NOT a global priority. I never want others to suffer the way that I did, and because of that it is now my mission to raise awareness & funds that will help eradicate this life-altering disease. Portions of proceeds from every show on the rest of the #HeadAboveWater tour and merch sales will continue to go directly to Lyme disease. I will continue to fight and to support! @TheAvrilLavigneFoundation supports people with Lyme Disease, serious illness or disabilities. We raise awareness and aid PREVENTION of the Lyme epidemic. We impact the lives of individuals and families affected by Lyme Disease through TREATMENT grants administered by our charitable partners; and we’ve aligned with @globallymealliance to accelerate scientific research. Please, JOIN US as we endeavor to educate people, prevent the spread of Lyme and find a cure. Our initiatives enable us to provide HOPE and expand the number of lives we’re able to transform. TOGETHER we can do this. #FightLyme #LymeIsReal #TheAvrilLavigneFoundation

Bieber’s reveal follows the announcement of a new album and tour, as well as a docu-series with YouTube that will premiere on January 27. The series will reportedly deliver more details on his journey with Lyme in addition to discussing his musical hiatus and marriage.

Lyme disease is transmitted through the bite of infected ticks, with symptoms usually including fatigue, fever, and skin rashes. If not treated, Lyme disease can also spread to the heart, joints, and nervous system. According to the CDC, 30,000 cases of Lyme disease are reported in the US every year.
