The pop superstar's promoters announced that Saturday night's (11Oct08) concert in Connecticut would go ahead after a string of cancellations, dating back to the end of September (08) - but now the show is off.

In a statement, her representative says, "Janet Jackson’s anticipated return to her Rock Witchu tour in Uncasville has been postponed due to doctor’s orders.

The singer now plans to resume the tour on Monday (13Oct08) in Verona, New York.

Jackson pulled her first show in Montreal, Canada on 29 September (08) after checking into a city hospital with a mystery illness.

She has since scrapped a series of U.S. dates on the Rock Witchu tour.

No official explanation for the latest cancellation has been given.
