Cher has canceled the remainder of her tour.
The pop diva was supposed to start a second leg of her Dressed to Kill tour in September, but she was forced to postpone due to an "acute viral infection" that affected her kidney function.
Although Cher's "progress has been consistent," her doctors have advised her to continue to rest.
Nearly 30 dates were scrapped, including stops in New York, Ohio, Michigan and Texas.
"I am totally devastated. Nothing like this has ever happened to me," she wrote on her website on Thursday. "I cannot apologize enough to all the fans who bought tickets. I'm so proud of this show. It is my best ever. I sincerely hope that we can come back again next year and finish what we started."
In March the 68-year-old launched what was billed as her final tour, nearly a decade after the end of a previous farewell trek.
The elaborate show -- featuring all the gawdy costumes, dancers and flashy production elements expected of a Cher show -- was sold out in nearly 50 cities, including its stop at Staples Center in July. The show was on hiatus when she contracted the virus.
Cher also took to her Twitter account on Friday to apologize to fans and share her heartbreak over the tour coming to an end.
"I Was Having SO Much Fun & Am SO SAD. It's like when u r a kid & trip2 Disneyland is Canceled," she posted.
