Nicole Richie has finally confirmed what ENQUIRER readers have known for weeks — she’s pregnant! The ENQUIRER broke the news in our our June 11th issue.

“I’m almost four months,” Richie tells ABC’s Diane Sawyer in an exclusive interview which will air on Good Morning America Thursday and on 20/20 on Friday night.

The Simple Life star — who was just sentenced to four days in jail after pleading guilty to DUI charges — also speaks out about how she thinks her actions have affected her young fans. “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.”
