Madonna Cancels London Concert Amid Injuries — But Insists, 'I Will Keep Going Until I Cannot'

Madonna is getting candid about current health struggles, forcing her to cancel another show date.

The singer, 61, opened up on Instagram Saturday about having to forgo performing at her first London show date on her Madame X Tour, offering apologies to her fans but insisting the show will go on as long as she is able.

“I am deeply sorry that I have to cancel my concert scheduled for Monday January 27th in London,” Madonna wrote, captioning a photo of herself sitting with what appears to be a cane. “Under doctors guidance I have been told to rest for a few days. As you all know, I have injuries that have plagued me since the beginning of the tour but I must always listen to my body and put my health first.”

“The last thing I want to do is disappoint my fans or compromise the integrity of my show. So I will keep going until I cannot,” she continued. “As always — anyone who purchased a ticket will be refunded for tickets purchased that evening. The show on Wednesday January 29th will go as scheduled.”

The “Vogue” powerhouse concluded, “Again I am deeply sorry to disappoint anyone and please know that it hurts me more than you can imagine to have to cancel any shows. Thank you again for your understanding. 🙏🏼.”
