The star was set to hit the stage in four consecutive gigs as a support act on Beyonce's The Mrs. Carter Show tour, but promoters at International Entertainment Groups have confirmed she will only be able to perform at the Allphones Arena on 3 November (13).
The rapper was also due to take to the stage on 31 October (13) and 1-2 November (13) but will now be replaced by singer Stan Walker.
Azalea took to Twitter.com to share the news with fans, writing, "Hey guys, just to clear any confusion. I am coming to Aus (sic) for the Beyonce tour, but due to an earlier commitment we made to vevo... I can only do the last sydney date of the sydney shows. I am on the rest of the tour though. I am very sorry, we tried to work around it."
