Katherine Heigl Advocates Electronic Smokes

I just don’t like Katherine Heigl. I’m not really sure why. She just seems like if you met her in real life, she would be an uber bitch. And what’s the deal with her hair color? It’s very yellow.

In the clip, Heigl – promoting her film Life As We Know It – talked to David Letterman last about her trying to quit smoking and all the steps she’s taken in her attempts to quit.

She then whips out the electronic cigarette and shows Dave how to smoke on tv and he looks to be enjoying himself, in a Mad Men way.
