Madonna has cancelled the first London show of her 'Madame X' tour after being advised to rest by her doctor.
In a post on instagram, she apologised to her fans for the cancelling Monday's show at the London Palladium "under doctors' guidance".
"Please forgive this unexpected turn of events. Doing my show every night brings me so much joy and to cancel is a kind of punishment for me," she wrote.
"But the pain I'm in right now is overwhelming and I must rest and follow doctors orders so I can come back stronger and better and continue the Madame X journey with all of you."
Ticketholders will be refunded, with her next concert on Wednesday set to go on as planned.
