So there is a baby bump behind that giant purse Nicole Richie has been carrying around! In a new interview airing on Good Morning America Thursday and on 20/20 Friday, Nic tells Diane Sawyer that she and boyfriend Joel Madden are, indeed, expecting a little one. "Yes I am. We are. I'm almost four months," she says. As for her guilty plea in the DUI case last Friday, where she was sentenced to serve four days in jail, Nicole told Diane: "I have a responsibility and it's something that I did wrong, and if I could personally apologize to every single person that has lost a loved one from drunk driving I would. And unfortunately I can't, but this is my way of paying my dues and taking responsibility and being an adult." I'm happy for Nicole --- can't wait to see what that girl looks like with a big, round pregnancy belly!
