Anastacia has had to cancel her tour after being diagnosed with breast cancer for a second time.
The US singer, whose European tour was due to begin in London in April, announced the sad news on her Facebook fan page
"Anastacia has sadly been diagnosed with breast cancer for the second time after having successfully survived her 2003 battle with the disease.
Consequently she has been forced to cancel all performances, tours and any travel from now until further notice."
The I'm Outta Love singer told her fans: "I feel so awful to be letting down all my amazing fans who were looking forward to It's A Man's World Tour. It just breaks my heart to disappoint them."
The statement said that Anastacia will continue writing and recording her new album despite the diagnosis and that she hopes to schedule a new tour as soon as possible.
"Now more then ever, she is determined to live by her motto 'Don't ever let cancer get the 'Best of You!'," the statement, referring to the name of her recent song, said.
