Jimmy Kimmel hosts the late-night show Jimmy Kimmel Live on US TV network ABC Jimmy Kimmel's "Worst Twerk Fail ever" video was posted on YouTube last September and gained nine million views before the talk show host revealed it had been a set-up.
The clip appeared to show an amateur dancer twerking against a door in her apartment, before falling over onto a table and setting fire to her leggings.
But a "director's cut" of the video, broadcast on Kimmel's nightly show ended with the presenter appearing from behind a door and putting out the flames with a fire extinguisher.
He also revealed the supposed star of the video, Caitlin Heller, was in fact a Hollywood stuntwoman called Daphne Avalon.
