Grey’s Anatomy star Katherine Heigl says when she wants kids, she’ll adopt, rather than give birth to her own. Engaged to musician Josh Kelley, Heigl says she was turned off of the idea of becoming pregnant after shooting a scene for her upcoming feature film Knocked Up, in which her character undergoes the extremely painful and agonizing delivery of her first child. She told USA Today: “I’ve always planned to adopt anyway, but that definitely reinforced my want to. I’m done with the whole idea of having my own children. (It) doesn’t seem like any fun. I don’t think it’s necessary to go through all of that.” Knocked Up opens June 1st.
