LOS ANGELES (AP) - After months of rumors, Nicole Richie has confirmed that she is indeed pregnant.
Richie says she's "almost four months" along.
Richie says her boyfriend, Good Charlotte frontman Joel Madden, is the father.
The 25-year-old star of "The Simple Life" and on-again pal of Paris Hilton also talked with Sawyer about her guilty plea last week to driving under the influence and resulting four-day jail sentence.
Richie says if she could "personally apologize to every single person that has lost a loved one from drunk driving," she would.
Richie also shared her thoughts on her hard-partying contemporaries and what effect their bad behavior has on young fans.
The interview will air on "Good Morning America" on Thursday and Friday and on "20/20" Friday night.
