In a since-deleted Instagram post from January 2020, Justin Bieber revealed to his followers that he had been battling Lyme disease, which is caused by an infection commonly carried by ticks. "While a lot of people kept saying Justin Bieber looks like s***, 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 (via CNN), adding that he'd explain more in his YouTube docuseries, "Seasons."
Per TMZ, Bieber's Lyme disease went undiagnosed for the majority of 2019, but he was of course, photographed incessantly during that time — after all, he is one of the most famous singers in the world, and it's hard to hide from the paps when all eyes are on your every move 24/7. However, in an Instagram Story from August, Bieber pleaded with the media to stop using photos of him from that time period, writing in part, "I'm still in shock we are still using these photos of me, I'm telling you media wants to pick bad photos of me to make it look like I'm not okay" (via Page Six).
