Halsey's Scary Diagnosis
Halsey received overwhelming support from fans over her diagnosis.
Halsey first opened up to fans about her autoimmune disease in June 2024.
"I realize everyone is catching up with news I've held in for a very long time, and I wasn't sure how much I wanted to share," she wrote in an Instagram post at the time. "You've all been so kind so I want to share a bit more. In 2022, I was first diagnosed with Lupus SLE and then a rare T-cell lymphoproliferative disorder. Both of which are currently being managed or in remission."
Halsey is starting her tour this October.
The "Eastside" artist concluded, "After a rocky start, I slowly got everything under control with the help of amazing doctors. After 2 years, I'm feeling better and I'm more grateful than ever to have music to return to. I can't wait to get back where I belong: With you all. Singing and screaming my heart out."
