Cher's North American 'Dressed To Kill Tour', which began in March, was a major success - Pollstar named it the top female tour of 2014 by mid-year.
However, from September-onward, Cher was forced to postpone the tour several times due to having an acute viral illness that affected her kidney function.
Her rep told fans earlier this month that the singer was "healthy" and had "beaten the illness" and thus would return to the stage during November though the tour was postponed once more to December as Cher's doctors advised her to rest.
It has now been announced, however, that the tour has been cancelled altogether - a press release for the 'Believe' singer states:
"With enormous regret, Cher has announced the cancellation of all remaining dates on her 'Dressed To Kill (D2K)' concert tour
"Beginning in March, the multi-award-winning superstar completed 49 sold-out concerts to unanimous rave reviews before taking a scheduled break in July.
"Shortly before returning to the road in September, she was felled by an infection that affected her kidney function.
"While her progress has been consistent, Cher's doctors have advised her to take more time to ensure complete and total recovery."
On the other hand, Cher herself has avoided using the word "cancelled" and hopes that the tour will resume next year - she herself stated in the press release; "I am totally devastated.
"Nothing like this has ever happened to me. 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".
After the press release hit publication, Cher went on Twitter to tell her fans, "I'm sorry I couldn't be the one to tell you about postponing my tour. I tried so hard to be strong enough, but my will couldn't force my body time."
This wasn't the only bad news for Cher; Mike Nichols, the director whom cast her alongside Meryl Streep in 183's 'Silkwood', sadly passed away this week.
Cher tweeted about the tour, "Let's talk about it tomorrow. Between gut-wrenching sadness of not being able to go onstage, sing, be silly, wear new Bob Mackie costumes and Mike dying, I'm heart-broken."
