Nov. 16 (UPI) -- Mariah Carey announced on Twitter Wednesday that she is canceling the opening shows of her Christmas concert tour due to an upper respiratory infection.
"Lambs! Just in time for the holiday gift-giving season, it seems I've received a present of my own; a lovely upper respiratory infection after last week's flu," the singer wrote.
"Bleak! You know there is nothing I love more than celebrating the holidays with my festive Christmas show, but I have to take my Doctor's orders and rest until he says I can sing on stage," Carey continued.
"Until then, unfortunately, I have to cancel the first several shows of my upcoming Christmas tour. I'm going to do all that I can so that I can see you soon!"
The Christmas tour was originally scheduled to begin Friday in Windsor, Ontario, at The Colosseum at Caesars Windsor. The concert series will now begin on Nov. 27 at the Beacon Theatre in New York City before wrapping up Dec. 22 at the Colosseum in Las Vegas.
