Nicole Richie and live-in boyfriend Joel Madden sat down with ABC News anchor Diane Sawyer to talk about life, love, jail, and motherhood. That’s right, Nicole has finally ‘fessed up – she’s four months pregnant. The interview, which will air Thursday and Friday, will feature a Nicole who seems to express remorse for some of her more wild ways. The celebutante seems perfectly ready to accept responsibility for her actions, beginning with a jail sentence she’ll begin before September. Richie pled guilty to the charges and will spend four days behind bars. Richie will also be featured in OK! magazine, to hit the stands Friday. Joel Madden has been dating Richie four about seven months, a relationship beginning just when Madden split from famous former tween Hilary Duff. Some rumors suggest the two may tie the knot this summer, though Richie has not confirmed these plans.
