A representative for Janet Jackson says the singer has been hospitalized after falling ill shortly before a concert.

According to statement released by W&W Public Relations, the singer canceled her concert in Montreal on Monday (9/29) after she "got suddenly ill" during her sound check and had to be rushed to the hospital just before show time.  Last Friday, Jackson canceled the weekend Detroit stop of her Rock Witchu road show due to "production constraints."

The announcement was made to fans five minutes before LL Cool J was about to open for the star.

The statement says Jackson, 42, is being monitored at the hospital and hopes to reschedule the show.  No further information was given about Jackson's condition.
