Justin Bieber has confirmed that he's been diagnosed with Lyme disease.
The star also attributes a "serious case of chronic mono" to why he hasn't been looking his best recently. He says the ailments have affected his "skin, brain function, energy and overall health."
The Bieb, who sparked rumors of a breakdown when he was seen crying in October, promises to reveal his medical issues in a docu-series that will hit YouTube on January 27th.
In an Instagram post, he says, "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."
Lyme disease is no joke. It can cause fatigue, joint pain and weakness in the limbs.
