Nicole Richie is preggers

So, I just recently developed a liking for babies. They're so cute.. now that I'm older. So I'm happy for Nicole Richie if she's going to have a baby with Joel Madden, but a few questions popped into my mind:
1. Can a fetus have an eating disorder?
2. Can her frame carry a child?
3. Why would you have raw sex with a Madden brother?
4. Will DJ AM be taking a paternity test?
