Lady Gaga has cancelled the last 10 dates of her world tour due to "severe pain".
A statement posted on Twitter said the pain had "materially impacted" her ability to perform, and that she was receiving medical care.
The statement said:
“Unfortunately, Lady Gaga is suffering from severe pain that has materially impacted her ability to perform live. As a result Live Nation and Lady Gaga are announcing the cancellation of the final 10 dates of the European leg of her Joanne World Tour. Last night, with strong support from her medical team, Lady Gaga made the tough decision to immediately come off the road. She is extremely sorry and deeply saddened that she cannot perform for her European fans, who have waited so patiently.
“She is in the care of expert medical professionals who are working closely with her so she can continue to perform for her fans for years to come.
“Ticket holders may obtain a refund beginning Tuesday 6 February at point of purchase.”
Lady Gaga said "I'm so devastated I don't know how to describe it". She revealed last year that she had been diagnosed with fibromyalgia, a condition that can cause sufferers to feel pain all over their body.
She apologised to fans but said she had to "put myself and my well-being first".
“I’m so devastated I don’t know how to describe it. All I know is that if I don’t do this, I am not standing by the words or meaning of my music. My medical team is supporting the decision for me to recover at home. We’re cancelling the last 10 shows of my Joanne World Tour," Gaga said. "I love this show more than anything, and I love you, but this is beyond my control. London, Manchester, Zurich, Koln, Stockholm, Copenhagen, Paris, Berlin. And Rio. I promise I will be back in your city, but for now, I need to put myself and my well-being first. I love you, forever. XX Gaga."
