EDITOR'S NOTE: Since this article's original publication on January 18, Janet Jackson has expanded her North American tour by five dates. The itinerary below has been updated to reflect Jackson's current schedule as of January 26.

Though her last North American tour didn't fare so well, Janet Jackson is ready to give it another go with a fresh batch of spring concert dates for her new tour, Number Ones, Up Close and Personal.

When the '80s music icon hits the circuit in March, she'll be routed through more intimate venues than the arenas she booked for the dud 2008 Rock Witchu Tour. But Jackson will also keep the setlist familiar, selecting songs exclusively from her 2009 compilation of number one hits.

Japan will have to wait for Janet Jackson’s Rock Witchu tour until later this year.

The Grammy winning singer was scheduled to perform five shows from February 14-22, but the upcoming tour has been postponed "due to the impact of economic crisis," according to her Japanese promoter, Kyodo Yokohama.

Janet Jackson just can not get a break on her first North American tour in seven years.

First, she had to cancel a string of nine concerts because of migraine-associated vertigo that causes dizziness and imbalance. Now, she lost her opening act. Rapper LL Cool J pulled out of the tour, citing unspecified "scheduling conflicts." The announcement came in an October 27 Associated Press report based upon a statement from his publicist, and LL Cool J was a no show at the October 22 concert in Dallas, TX. No replacement has been named as of yet.

Janet Jackson's October 11 concert at Mohegan Sun in Uncasville, CT, was supposed to be her comeback show after a string of postponements because of an undisclosed illness. But one day after the announcement of her return came news of yet another postponed show, now numbering seven, since she became ill during a soundcheck in Montreal on September 29.

Additionally, Jackson was scheduled to hit the stage at the Turning Stone Resort & Casino in Verona, NY, on October 13, but the performance was postponed due to doctor's orders, according to a post on the venue's Web site. Tickets will be honored at a rescheduled date to be announced soon.

Having already cancelled four concerts recently, Janet Jackson has postponed three more shows because of an undisclosed illness. Affected shows are October 4 in Greensboro, NC; October 5 in Atlanta, GA; and October 7in Fort Lauderdale, FL. All refunds are available at the point of purchase, but ticket holders have been advised that tickets can be used for rescheduled shows.

Jackson tried to perform at Greensboro after arriving at the city, but a local doctor advised her not to perform until she was fully recovered from her illness. Her next scheduled show is October 11 at the Mohegan Sun casino in Uncasville, CT.
