Strange things happen to women when they get pregnant, but it’s hard not to look at some celebs with a cynical eye. How is it possible, for instance, that a party girl and troublemaker, reality star and celebutante, could suddenly become a responsible adult? Believe it or not, Nicole Richie seems ready to accept that role.

The expectant starlet recently delayed her wedding to boyfriend (and father-to-be) Joel Madden, but she’s moving forward with other areas of her life. Now that she’s going to be a mother herself, Nicole is looking for a way to bury the hatchet with her biological parents, people she’s had a rocky relationship with from the age of three. Nicole plans to open up about her biological parents in an upcoming interview, and hopes to pave the way for a future relationship.  Meanwhile, the postponed nuptials will take place after the birth of her baby - the sex of which Richie has opted to not learn.

Once, she was a sidekick to frenemy Paris Hilton. Now, she’s a young mother-to-be doing her best to bridge the gap between her past and the future. Unbelievably, it looks like Miss Richie is finally growing up.
