Kate Moss plays George Michael's ''saviour'' in his new music video.

The British supermodel has a cameo role in the film which accompanies his forthcoming single 'White Light' - which the 'Careless Whisper' star wrote following his battle with pneumonia last year - and the singer has teased details of her appearance in the clip.

George tweeted: ''By the way,in the video, a certain supermodel (our Kate) saves my life. We shot two endings, one with the heimlich menouvre...and one where she gives me full on CPR. Mouth to mouth.

''Not really:} But honestly, she is my saviour, on film at least! (sic)''

Meanwhile, George has also revealed his favourite lyric from the new song after asking fans if they could guess what they thought it was.

He retweeted one fan who wrote ''was it science that saved me? Or the way that you prayed for me? ..'' and then replied to her ''Bingo!''

And though the track is currently number one on online retailer Amazon's singles chart - based on pre-orders - George, 49, has appealed to fans to bombard radio stations with requests for the song to be played.

He wrote: ''Every radio request from you guys is much appreciated, remember I'm twice the age of your average popstar these days!! So keep on calling those requests in....Help the Aged :)) (sic)''
