U.S pop sensation Ke$ha stunned crowds at an Australian music event after drinking blood from a heart live on stage. 

The star was performing her track, 'Cannibal', at Future Music Festival in Brisbane when she took out what was thought to have been an animal's heart and poured 'blood' into her mouth and onto her chest before continuing with her set stained with the crimson substance. 

Ke$ha will come to the UK in July to appear at Scotland's T in the Park event and you can watch part of the much talked about performance here:
