Kesha has now proven to be the most bloodthirsty of popstars - literally.
According to PopDust, her recent set at the Brisbane Future Music Festival featured the 'Tik Tok' 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. Watch a 'bloody' performance by Ke$ha after the jump.
