Sad but true: Amy Schumer won't be heading Down Under this week.

Live Nation announced Monday that the comic will no longer be performing in Brisbane, Melbourne, Sydney and Perth this month. Her tour was set to start Saturday at Perth Arena.

The promoter cited illness as the reason for Schumer's cancellation. "Unfortunately, due to Amy Schumer's tight schedule it is not possible to schedule replacement dates," Live Nation added. "However, we will be working to confirm a return to Australia as soon as is practical."
