Sept. 4 (UPI) -- U.S. pop star Lady Gaga says she is ill and must postpone Sunday night's concert in Montreal.
"I couldn't be more devastated that I am unable to perform tonight," the singer tweeted in a message to her "beautiful fans," which accompanied a photo of her with her hand over one of her eyes.
"I sing this entire show live, and pride myself in giving it all, but when I sang in the rain at Citi Field I got sick and have been pushing through. I am so sorry to anyone that had their heart set on seeing me tonight. I love you."
I'm so sorry Montréal. We are working on postponing the show. Please read this message from my ❤️ below. pic.twitter.com/ktglIGpykL— xoxo, Gaga (@ladygaga) September 4, 2017
