Def Jam released a statement to announce that the tour will not go ahead as planned this spring because of artistic concerns.
A Def Jam spokesperson told Billboard, "To accommodate for creative team availability and tour productions, it was determined that the tour will not be ready this spring.
"It's important to Iggy that she delivers the show she envisaged to share with her fans and that requires more time in development."
A representative for the 24-year-old rapper also denied that conflict between Azalea and her management led to the tour postponement.
