So fucking disgusting!
Katherine Heigl is such a pretty girl, but she's also one of the filthiest smokers in Hollywood.
The actress was spotted sucking on a cancer stick on the way to Prospect Studios in L.A. on Thursday to film Grey's Anatomy.
We need to personally go out and buy her a bunch of that dissolvable tobacco, Ariva, that Lindsay's been hawking lately.
Hopefully Katherine will finally give up her dirty habit!
