Heeeere’s Johnny — smoking a fake cigarette?

Once known for puffing all things smokable — both legal and illegal — iconic actor Jack Nicholson appears to have given up the real thing for hot air.

The Oscar winner with a legendary taste for stogies, cigarettes and other forms of burning leaves signed autographs in LA yesterday with an electronic cigarette dangling out of his mouth.

He appears to be putting his health first and buying into the increasing popularity of the fake sticks.
