The ‘Rock Witchu’ Tour has come to a screeching halt again this weekend. According to a statement released early this morning, Jackson has cancelled tonight’s ‘Rock Witchu’ re-launch in Connecticut. “Janet Jackson’s anticipated return to her Rock Witchu tour in Uncasville, Conn., has been postponed due to doctor’s orders,” a rep for Live Nation said in a statement to Access Hollywood. This will be the seventh show that the Grammy-winning pop diva has been forced to postpone since falling ill during a sound check in Montreal. No details have been forthcoming about what exactly is plaguing the 42-year-old artist. As has been the case with other missed dates, tickets for the Uncasville show will be honored when the gig is rescheduled.
