Lady Gaga may thrive on the applause, but she'll have to wait a little longer to receive it from the Montreal audience once again. Just hours before the "Abracadabra" singer was scheduled to perform in the Canadian city as part of her Mayhem Ball Tour, she announced that she had to cancel her concert due to a respiratory infection.
"I'm so sorry to share that I'm unable to perform tonight and have to cancel the show," Gaga shared in an April 6 statement on her Instagram Story. "I've been battling a respiratory infection for the past few days and have been doing everything I can to rest and recover, but it's gotten worse."
Although she was hoping to power through her third performance in Montreal, Gaga and her doctor ultimately knew that the show couldn't go on. "My doctor has strongly advised me not to perform today," the 40-year-old wrote. "And to be honest, I don't think I could give you the quality of a performance that you deserve today."
"I know how deeply disappointing this is," she continued. "And I truly couldn't feel worse about letting you down. I'm so sorry to everyone who made plans to be there and support me."
In a final note, Gaga (real name Stefani Germanotta) praised the Montreal audience who were there for her April 2 and 3 shows, before offering one last apology to her fans. "Being in Montreal and performing for you on Thursday and Friday was magical and deeply meaningful," she concluded. "To everyone who was coming tonight, I'm absolutely heartbroken and so sorry."
At this time, it is unclear if the canceled show will be postponed to a later date. The "Just Dance" hitmaker has been on tour since July 2025. She is next set to take the stage on April 9 and 10 in Saint Paul, Minnesota, before heading to New York City to conclude her 86-show tour.
But the tour isn't the only thing that has kept Gaga busy lately. She also attended the 2026 Grammys in February, where she took home the Best Pop Vocal Album trophy for Mayhem, and has been busy planning her upcoming wedding to fiancé Michael Polansky.
Although Gaga is staying coy about the details of their big day, she did share one detail that will be a non-negotiable in her eyes. "I'm desperately trying to keep that so private," she told E! News in March 2025. "But I can promise that it will be the best day of my life."
