Celine Dion has cancelled her scheduled concert in Chicago tomorrow night (04.11.08), after doctors banned her from singing for five days.
The 40-year-old singer - who had a special humidifier built to protect her throat during her Las Vegas residency from 2003 to 2007 - is unable to perform because she has been battling a nasopharyngeal infection, an infection in the upper respiratory tract, for the past week.
Celine has rescheduled the concert for December 16 but she is still set to perform on November 7 in Ottawa, Canada, as part of her 'Taking Chances World Tour'.
The singer recently revealed she and her 66-year-old husband Rene Angelil will try for another baby after she finishes the tour.

Victoria Beckham has reportedly snubbed an invitation to Mel B’s wedding.
Mel, 33, is renewing her vows with film producer husband Stephen Belafonte in a four-day ceremony in Egypt this week, following their 2007 marriage in Las Vegas.
Victoria, 34, and her soccer star husband David Beckham were invited but won’t be attending, and it is not known if any of the other Spice Girls –
Geri Halliwell, Emma Bunton and Mel C – will be going on the lavish, all-expenses paid trip either.
Mel had also invited Girls Aloud singer Sarah Harding, British TV presenter Fearne Cotton and former S Club 7 star Rachel Stevens to the ceremony, but none are able to attend.

It's so much fun. It's where I come from so I'm very comfortable to go back to that.”
