The stage set for the star's 'All For You' tour is not quite ready...

JANET JACKSON has been forced to cancel the opening night of her north American tour tonight (July 5), because the stage set is not finished.

According to sources in Canada, the pop superstar’s lavish set for her ‘All For You’ world tour is still under construction, leading to the opening night at Vancouver General Motors Palace being cancelled.

It is as yet unclear whether dates at Portland Rose Garden Arena in Oregon on July 7 or Key Arena at Seattle Centre on July 8 have been affected.

NME.COM understands that the Vancouver show will now take place on Monday (July 9). More information is expected soon.
