12. Kate Bosworth

As all smokers can confirm, cigarettes can be really persistent, especially when you are trying to quit. Even actress Kate Bosworth is able to confirm this, since she couldn’t stop smoking while rigorously preparing for a movie role.

Bosworth got her shot at fame with a role in 2002’s “Blue Crush.” And for her part of a sexy professional surfer, she had to train like a maniac 7 hours a day for 2 months. However, even though the actress had very little time to rest, she still managed to find a few minutes every now and then for a cig.

Kate still smokes today, and is living proof of how addictive cigarettes can be.
