KeshaKe$ha's recent set at the Brisbane Future Music Festival featured the singer in a tattered American Flag performing recent hits before kicking off her upcoming '$leazy' tour.

But the show didn't escalate into performance-artist antics until halfway through 'Cannibal,' when Ke$ha pulsed blood from a dissected heart into her mouth and over her body.

No word on whether the heart was from the animal kingdom or a prop, but one thing is for sure - pop music just got a lot crazier. .
