Simon Cowell is apparently doing his best to quit his 40-a-day smoking habit.
The Britain's Got Talent star - who has previously admitted he loves smoking and is rumoured to have "smoking minders" when he goes outside for his nicotine fix during TV talent show auditions - is trying to cut down using electronic cigarettes.
Fellow Britain's Got Talent judge Amanda Holden told The Daily Mirror: "Simon does not smoke any more. He has got a vaporising cigarette instead.
"He smokes air, or rather water. It's amazing."
Electronic cigarettes work by inhaling nicotine, and at the same time sucking in water from the atmosphere and releasing vapour that looks like smoke.
Since smoking was banned the devices have become a huge hit in Los Angeles - where Simon has a home and is based for six months of the year - so that stars can continue to smoke indoors.
Simon, 53, previously said: "I genuinely still love smoking; I equate smoking with having a good time.”
