This Will.i.am Performance Will Melt Your Mind

    What is happeniiiiing.

    So last night was the finale of The Voice Australia, and will.i.am's singer Anja Nissen took out top spot.

    #congratsANYA @anja_nissen winner of #theVOICEau #teamWILL

    But the really mind-blowing part of the night came from will.i.am's own performance.

    He took the stage with Cody Wise to perform "It's My Birthday", and at first things seemed... fine.

    Until the dude playing the keyboard looked suspiciously like will.i.am in a bandanna.

    And then... another Cody appeared?

    And woah wait that is definitely will.i.am playing the drums.

    And also IN THE AUDIENCE?!

    Wait whaaaaat?

    What is this madness?!

    Oh nothing much just will.i.am taking the ultimate selfie.

    And falling down and laughing at himself.

    And flipping himself off.

    It was just like...

    What?

    The other judges were pretty into it.

    But everyone watching along at home was very confused, afraid, and basically questioning their entire existence.

    I have no idea what just happened #TheVoiceAU

    My brain hurts a little, but wow. #TheVoiceAu @iamwill #birthday

    I think @iamwill just broke the minds of Australian TV viewers. #thevoiceau

    You've all seen The Prestige? Yeah, http://t.co/HNqaJtug4F is drowning his clones in the ad break. #TheVoiceAu

    My head hurts. Is this entire performance a hologram? #thevoiceau

    I need a nap. A hug. And a promise never to celebrate anyone's birthday again. #thevoiceau

    Still mindfucked over @iamwill's extraordinary performance on @TheVoiceAU #howdidhedothat #thevoicefinale #TheVoiceAu
