Janet Jackson has announced details of her first tour in seven years.

The pop singer kicks off her 'Rock Witchu' tour in Vancouver this September, with a full itinerary expected to be announced soon. The tour will see her promote tracks from her recent album 'Discipline' and her 2006 Greatest Hits collection.

It is not yet known whether she'll play any European dates.

She told the Associated Press: ""I was supposed to go on tour with the last album. We were actually in full-blown tour rehearsals at that point...learning numbers, getting everything together, set designs, [but then] I had to kind of shut everything down and go into the studio."
