US rapper Nicki Minaj's second Australian tour for 2012 has been postponed, just hours before it was due to go on sale to the general public.
Minaj was set to perform in Brisbane, Sydney, Melbourne and Perth in September and October - but these dates will be rescheduled for November, according to tour promoter Live Nation.
The promoter apologised to fans, saying the charges "have become necessary due to international scheduling conflicts that also affect Nicki's European dates".
Live Nation also moved to reassure fans that Minaj will make it back to Australia in 2012 despite the hiccup, and said the full details will be announced shortly.
