All About Her Lupus, T-Cell Disorder & More – Hollywood Life

Halsey has managed several health issues and setbacks over the years, but they haven’t let it affect their career. The “Gasoline” artist, who prefers she/her and they/them pronouns, is an open book about her lupus condition, T-cell disorder, endometriosis and other challenges.

In September 2025, Halsey updated fans via TikTok that she’s undergoing chemotherapy ahead of her Back to Badlands Tour.

“Just coming on here to give you guys another speed round of updates. [I] just did another few sessions of chemo,” the singer said. “[I] had a new port placed. … My birthday’s in a couple of days. I’m so busy, I haven’t even honestly thought about it at all.

Halsey also joked about a comment that their fiancé, Avan Jogia, made about her upcoming tour, which will kick off in October 2025 at the Hollywood Forever Cemetery in Los Angeles.

“Really funny story, me and Avan were driving in L.A. the other day and he pointed to Hollywood Forever Cemetery, [and] he looked at me and he went, ‘You’re gonna be in there soon,’” Halsey recalled. After expressing her initial shock at the comment, the “Without Me” hitmaker added, “He was like ‘Oh my God, I mean for your show, for the first show of your tour.’ I was like, ‘Oh OK, that’s way better than what I thought you meant.’ Can’t wait to be in there soon.”
