It's hard to know who to feel more sorry for--Janet Jackson, who's taken ill in the middle of her first North American tour in seven years, or her fans who keep getting cancelled on.

On Monday, a doctor ordered the singer to postpone her Rock Witchu tour once again, forcing the shutdown of tonight's performance at the Turning Stone Resort in New York.

A message posted on the resort and casino's website stated the show had been cancelled at the advice of Jackson's doctor.

The legendary singer has also postponed several more shows, including one on Thursday night at Madison Square Garden in NYC. Promoters say the dates will be rescheduled.

The source of the singer's ailment has yet to be disclosed. Jackson was rushed to a hospital in Montreal before a concert in late September.
