Lady Gaga has cancelled a concert in Montreal, Canada after being struck down with a respiratory infection.

The 40-year-old pop star had been due to play her third show at the Bell Centre in Montreal on Monday (06.04.26) as part of her Mayhem Ball Tour but she called off the concert after being "strongly advised" not to perform by her doctor.

In a post on Instagram, she explained: "Hi everyone, I'm so sorry to share that I'm unable to perform tonight and have to cancel the show. I've been fighting a respiratory infection for the past few days and doing everything I can to rest and recover, but it's gotten worse.

"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."

She added: "I know how deeply disappointing this is, and I truly could not feel worse about letting you down. I'm so sorry to everyone who made plans to be there and support me.

"Being in Montreal and performing for you on Thursday and Friday was magical and deeply meaningful. To everyone who was coming tonight, I'm absolutely heartbroken and so sorry."

Lady Gaga kicked off the tour in the US in July last year and the singer previously explained she hadn't planned to hit the road again so soon.

In a post on Instagram, she wrote: "I wasn't planning to tour this year after my shows in Singapore but the incredible response to the new album inspired me to keep things going.

"It came together super quickly thanks to Arthur Fogel and the amazing team at Live Nation, who planned a global tour in just a few weeks.

"We chose arenas this time to give me the opportunity to control the details of the show in a way you simply can't in stadiums - and honestly, I can't wait.

"This show is designed to be the kind of theatrical and electrifying experience that brings MAYHEM to life exactly how I envision it. The MAYHEM Ball Tour is officially coming your way. See you soon, monsters."
