Katherine Heigl Tries To Give Up Smoking With The Help Of...

Katherine Heigl is full of hot air. Hah!
The actress made an appearance on David Letterman‘s show and took the time to hawk her new favorite gadget, an electric cigarette.
Turns out Heigl’s trying to quit with a battery operated cig which is filled with liquid nicotine.
She inhales the harmful nicotine but just exhales water vapors.
Probably not the best thing for you, but talk about a great way to eliminate second-hand smoking.
Wonder how much $$$ she’s getting to promote the item.
