Will Nicole spill the baby-on-board beans to Diane?

Is she pregnant? Is she nervous about going to jail for her second DUI? Is she engaged?

Set your Tivo, folks. These and more important questions may be answered when Nicole Richie opens up to Diane Sawyer later this week on "20/20" and "Good Morning America." 

The interview is skedded to be aired Thursday and Friday morning. But she's already opened up to David Letterman. Appearing on his show recently, the scandalous "Simple LIfe" starlet said, "I really try and take everything that I go through as a life lesson and I try not to make the same mistake twice."

OK. Then why is this is her second DUI arrest?

Boy, I'll bet Diane is really looking forward to this interview. During her 20 year career, she's sat down with President Bush, the late Saddam Hussein, Fidel Castro; Robert MacNamara (for his public apology on Vietnam), Sammy "The Bull" Gravano, mob boss John Gotti, Ellen DeGeneres (she announced her homosexuality), ousted Panamanian leader Manuel Noriega, former first lady Nancy Reagan, and the Clintons after the 1992 presidential election.

From that to a celebutante starlet famous for her drug use, DUIs, foul mouth, stylist-manufactured fashion sense and emaciated frame. Talk about interviewing down ....
