Justin Bieber made a big confession yesterday while much of the media was focused on Meghan Markle and Prince Harry’s announcement they’re stepping back from their senior royal family roles: He has been diagnosed with Lyme disease and chronic mono. Many fans were supportive, and a few mocked the Biebs and the news.

Hailey Baldwin, Bieber’s wife, had a message for that minority on her Twitter. She defended her husband, writing to the trolls:

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. 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. Love you 3 amazing women! and sending so much love to @AvrilLavigne thank you for all you do to educate people about Lyme. You’re amazing.

When Bieber initially shared the news on his Instagram, he wrote:

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. 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
