Janet Jackson has been hospitalized with an undisclosed illness, resulting in the abrupt cancellation of last night’s (September 29) “Rock Witchu Tour” Montreal show. A representative for the pop star confirmed she suddenly became ill while completing a routine sound check. The cancellation was announced to disappointed fans just minutes before LL Cool J’s opening set. This marks Jackson’s second “Rock Witchu Tour” cancellation in three days, as last Friday (September 27) the singer nixed a show due to “production budget constraints.” At press time, Jackson, who recently severed ties with Island/Def Jam, remains in stable condition
