Janet Jackson cancels missed shows

(GREENSBORO, N.C.) Janet Jackson won't be rockin' any rescheduled tour dates.

The 42-year-old singer is not choreographing any makeup dates for the seven "Rock Witchu" tour performances that were initially postponed because of her illness "due to conflicts in the singer's schedule," said a statement released by tour organizer Live Nation on Tuesday.

The canceled stops, originally scheduled Sept. 29 to Oct. 13, include: Montreal; Boston; Philadelphia; Greensboro, N.C.; Fort Lauderdale, Fla.; Uncasville, Conn.; and Syracuse, N.Y.

Jackson's publicist previously said she had been suffering from migraine-associated vertigo, which led to her canceling the string of shows. She was being treated for the illness, which is characterized by dizziness, imbalance and other symptoms.
