Katherine Heigl On The Cover Of Healthy Living Magazine

HL: Who's your dream actor or actress to play opposite?

Katherine Heigl: I would love to work with Shirley MacLaine someday. I've been a huge fan, love her work and love her presence. I would love to work with Sally Field. I would love to work with Amy Adams someday.

HL: Your new movie Unforgettable is coming out this April. Playing a villain must be a dream come true for actors who are caught in sweetheart roles. How was it for you?

Katherine Heigl: It was a fascinating experience. And in a weird way, a little bit freeing to play somebody who is not going bend over backwards to make people like her or to please everyone. She is very, very self-interested—I don't recommend it. I don't think it's healthy but it was very interesting to be a tough ass for a little while. She is definitely very flawed, but I had a lot of sympathy for her as well and felt I'm kind of on her side honestly, despite her poor choices. I had a great time and it was wonderful to work with Rosario who is fantastic and I loved playing opposite her. I loved having a female director, Denise Di Novi, for this particular role and this particular story. It was a unique and wonderful experience.

HL: Tell us something about your lifestyle that you're most proud of?

Katherine Heigl: My fans and people know that, before I got pregnant, I was a smoker. I started it like a jerk when I was 25, which my mother gave me such a hard time about: "Well, you made it through high school, and your early 20s, and all that peer pressure. Why would you start smoking when you're old enough to know better?" Obviously I wasn't and I did, and it became a real issue for me. I had a hard time quitting. And the day I found out I was pregnant was the last cigarette I smoked. I immediately went to a hypnotist to help me quit because in the past I had such a hard time with it. I literally never had another one. It was not easy but it was not horrible. I didn't have crazy withdrawal or awful mood swings. I was able to just let it go and I don't know that I had a very important reason to let it go that was bigger than just me or if I finally was ready or if the hypnotist was that amazing but maybe it was a combination of all of that. Right now that's the thing I'm the most proud of is that I know I'm not going go back to it, and I was able to let go of this awful habit. I feel so much better not only about myself emotionally, but physically so much healthier and better. I'm so happy not to have this addiction hanging over my head.
