CONTROVERSIAL US comedy star Amy Schumer has been forced to cancel her Australian tour, days before she was scheduled to perform in Perth.

The tour’s promoter, Live Nation, said it “regretfully advised” that the tour had been cancelled because of illness.

“Unfortunately, due to Amy Schumer’s tight schedule, it is not possible to schedule replacement dates, however Live Nation are working to confirm a return to Australia as soon as is practical,” the company said.

Schumer, who is so popular Madonna became her support act at a recent stand-up gig at New York’s Madison Square Garden, was meant to perform at Perth Arena this Saturday.

The comic played an intimate stand-up gig in Melbourne while promoting her hit movie Trainwreck last year. Fast forward a year and she is the world’s most successful female comedian.

Her success earned her $17 million last year, making her the fourth highest-paid comedian and also the only woman to ever make the list of the world’s top-paid comics.

This world tour, which came with the warning that it would contain adult content, would have been her first Australian arena stand-up tour.
