Katherine Heigl is finally letting go of her biggest bad habit.

To set a good example for her 20 month-old daughter, Naleigh, she is going to quit smoking. But the process hasn't been easy – so she's resorting to interesting ways of curbing her cravings.

"Now I use an electronic cigarette. I know it's ridiculous, but it's helping me not to actually smoke real cigarettes," the actress tells "I've been doing it for six months. Smoking sucks!"

She adds: "The one thing I would say to my kid is, 'It's not just that it's bad for you. Do you want to spend the rest of your life fighting a stupid addiction to a stupid thing that doesn't even really give you a good buzz?' "

Heigl, 31, is also coping with another sensitive topic: kissing men that aren't her husband of almost three years, Josh Kelley, 30. As a romantic comedy darling, Heigl has had her fair share of onscreen lip locks, which makes Kelley a bit uneasy. "He and Josh Duhamel are good friends, but he would never come to the set when Josh and had to like kiss or make out. It does make him uncomfortable because he's not an actor, he's a musician," Heigl says of her husband and her Life As We Know It costar.

Heigl wouldn't be as squeamish if Kelley had a kissing scene, but on one condition. "He always says to me, 'How would you feel if I had to make out with some girl in a video?' And I'm like, 'If you have to do it, you have to do it, " she says adding, "but I wouldn't want you to come home and tell me what a great kisser she is and I should try her technique.' "

Sounds like all's fair in their house!
