Halsey reveals dual health diagnoses, debuts new song The End

Halsey has been privately battling illness, the singer revealed Tuesday.

She shared the news on Instagram in a series of videos that appear to document the singer receiving infusions.

"Long story short, I'm lucky to be alive," she wrote in the caption. "Short story long, I wrote an album."

In the initial post, an exact diagnosis was not immediately clear. Representatives for Halsey did not immediately respond to The Associated Press' request for comment.

"I feel like an old lady," Halsey says aloud in the first video, while rubbing her legs in apparent pain. "I told myself I'm giving myself two more years to be sick. At 30, I'm having a rebirth and I'm not gonna be sick and I'm gonna look super hot and have lots of energy and I'm just gonna get to re-do my 20s in my 30s."

But in a follow-up post on Wednesday, the singer disclosed they were diagnosed with systemic lupus erythematosus (SLE) in 2022, then later with " a rare T-cell lymphoproliferative disorder."

In that same post, Halsey went on to note that both are now in remission and are being managed, though they will likely remain as lifelong conditions.

"After two years, I'm feeling better and I'm more grateful than ever to have music to turn to," she wrote. "I can't wait to get back where I belong: With you all, singing and screaming my heart out."

The singer also released a new song on Tuesday, an acoustic guitar ballad titled The End. According to a media release, Halsey is making a donation to both The Leukemia & Lymphoma Society and the Lupus Research Alliance alongside the release of The End.

The single is an early release from Halsey's new album on the horizon — a follow-up to a fourth studio album, 2021's ambitious If I Can't Have Love, I Want Power, produced by Nine Inch Nails' Trent Reznor and Atticus Ross.

The new album was announced shortly after Halsey revealed a promotional, and cryptic, website: ForMyLastTrick.com.  Alongside images of a doctor X-raying a smiling woman and burnt cigarettes, the singer embedded a note:

"There's so much I am going to reveal on this record, but you need to know some of the story first," she wrote. "So before the chaos and confetti of big singles and album releases I just need to tell you, my friend, why it all matters this time."
