Justin Bieber confirmed on Instagram on Wednesday that he has been diagnosed with Lyme disease. Bieber’s Instagram post came after TMZ first reported that Bieber’s battle with the disease would be featured in his upcoming YouTube docuseries, Justin Bieber: Seasons.

“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,” Bieber wrote, adding, “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.”

Justin Bieber’s wife, Hailey Baldwin, whom he married in September 2018, thanked other celebrities for educating her on the condition. “I wanna say a huge thank you to @YolandaHadid and @bellahadid and @GiGiHadid for bringing me so much clarity and information on Lyme disease and for helping answer my questions about course of action, symptoms etc.,” Hailey wrote on Twitter. She followed up with another tweet which recognized Avril Lavigne’s work to educate the public about the condition. Yolanda Hadid, Bella Hadid and Lavigne all have the disease, as well as other celebrities including Ben Stiller, Shania Twain and Hailey’s uncle Alec Baldwin.

Hailey ridiculed those who doubt the severity of the disease, which so many people struggle with: “For those who are trying to downplay the severity of Lyme disease. Please do your research and listen to the stories of people who have suffered with it for years. Making fun of and belittling a disease you don’t understand is never the way, all it takes is educating yourself.”
