Richie, who is four months pregnant with boyfriend Joel Madden's child, insists that her wild partying and drug-taking days are behind her and now she wants to be a good mother, contactmusic.com reported.
Richie says she has gained 10 pounds already. "To me, numbers don't mean anything. If I gain 40 pounds, if I gain 50 pounds, then that's obviously what my body needs to do. I'm totally ok with that," she said.
