While Paris Hilton promised to fix her life after prison, nothing has really changed. Not so the case with Nicole Richie. Pregnancy is a defining moment for her and she has promised to become a good girl. Shockingly enough, she has given up drugs and alcohol as is often advised during pregnancy.

Apparently her Bible-thumping boyfriend Joel Madden has been a big help in turning her life around. "I owe the baby my life. I owe this baby everything and I have a responsibility now," Richie said in an interview with Diane Sawyer. "Besides being responsible for myself, I'm now responsible for someone else. And I have to set the right examples. I have to really be someone that I would want my child to look up to."

Good luck, Nicole.
