North West, the 13-year-old daughter of Kim Kardashian and Kanye West, has canceled her upcoming headlining tour with rapper Molly Santana. The tour, named Kimokawaii, was set to support her debut EP, NOrth4evr, and was scheduled to launch in Dallas on Wednesday, Aug. 5. The cancellation comes just days before the tour was to begin. West, who is the oldest of Kardashian and West's four children, had been building her music career and released the EP earlier this year. The tour had 14 dates planned. Neither West nor Santana has publicly explained the cancellation, but West said the tour is no longer happening. The news follows a period of increased musical activity for the teenager, who has been stepping further into the industry with her recent releases.
