Iggy Azalea has revealed that her biggest fear is vomiting on stage.

The Australian told Bang Showbiz that she is so overcome by the thought of throwing up whilst performing that she has drawn up emergency plans in her head.

The rapper said: "It's my actual nightmare to vomit on stage. If I ever vomited on stage, I would probably kill myself. I think if I start to feel like that, I have two plans, I would have already figured out my emergency exits. So if I can make it off stage, I will go off stage and vomit.

"If I feel like I can't make the wings, my poor DJ will hate me for it but I'll just run behind the DJ booth and vomit on his shoes. Poor DJ, but you don't want pictures."

Azalea meanwhile is due to release her debut album 'The New Classic' on Monday (April 21).

The Aussie recently confirmed plans to play at London's Shepherd's Bush Empire on September 17.
