TWERK VIDEO WAS A FAKE!

That 'Worst Twerk Fail Ever' video that went viral over the weekend WAS fake . . . and JIMMY KIMMEL was behind it. 

He made it a couple months ago, and waited for it to blow up.  So last night he had the woman in the video on as a guest.  She's a stuntwoman named Daphne Avalon.  And in the full version of the video, after she twerks, falls over, and catches on fire, Kimmel shows up with a fire extinguisher.
