The 'Father Figure' singer confirmed reports that Kate Moss will appear in the video, and that she will save his life on camera.
"In the video, a certain supermodel (our Kate) saves my life," Michael tweeted.
"We shot two endings, one with the heimlich manoeuvre… and one where she gives me full on CPR. Mouth to mouth. Not really ;}.
He added: "But honestly, she is my saviour, on film at least!"
Kate Moss is said to be a good friend and long-time fan of Michael.
The singer recently unveiled photo stills from the video, which included him appearing with a zebra.
'White Light' is available to download on August 12, 30 years after he first entered the UK singles chart with Wham!.
