Lady Gaga 'so sorry' to cancel concert at doctor's urging – 'Heartbroken'

Lady Gaga is recovering at the urging of her doctor.

The pop star took to social media to apologize to Montreal fans as she canceled what would have been her third and final Mayhem Ball Tour show in Quebec. She wrote on her Instagram stories Monday, April 6, "My doctor has strongly advised me not to perform today and to be honest I don't think I could give you the quality of a performance today that you deserve."

The "Dead Dance" singer, 40, said she contracted an upper respiratory infection a few days prior, and while she was "doing everything I can to rest and recover," it has "gotten worse."

"I know how deeply disappointing this is, and I truly could not feel worse about letting you down," she continued. "I'm so sorry to everyone who made plans to be there and support me. To everyone who was coming tonight, I’m absolutely heartbroken and so sorry."

The Grammy winner played two shows in Montreal on Thursday, April 2, and Friday, April 3. Gaga has been on tour since July, with over 80 dates volleying across North America, Europe, Australia and Japan. The singer previously postponed a Miami concert due to vocal strain.

She said at the time that a performance would have posed a "significant risk" and that while it was a "hard and agonizing decision," she "would be more afraid of the long term implications on my voice."

"I tried so hard to avoid this," she added. "I take serious care of myself to be able to put on this highly demanding show."

The award-winning tour is currently set to return to the U.S. on Thursday, April 9, and Friday, April 10, with back-to-back shows in Saint Paul, Minnesota, and a final concert April 13 at Madison Square Garden.

The Mayhem Ball Tour has been praised for its theatricality, production design, choreography and Gaga's vocal performance, in her highest-grossing tour to date. The tour was also the highest-grossing pop tour by a female artist and the second-highest overall in 2025.
