Nicole Richie's pregnancy has been confirmed.'The Simple Life' star is expecting her first child with Good Charlotte rocker Joel Madden and the couple are also said to be planning to marry this summer. Rumors about the 25-year-old's pregnancy have been circulating for months, but gossip website claim they have independently confirmed the news. Nicole's representative is still refusing to comment, saying: "We have nothing to report."Nicole's father, music legend Lionel Richie, admits he will be the last to know if his daughter is planning to start a family or marry this year. Lionel told Access Hollywood: "Nicole is probably one of those wonderful people that will not tell her father until I keep going, 'Come on Nic. I'm your father. What's going on?'"She'll say 'Nothing dad, nothing.' So right now, she's in nothing mode. I don't know. She'll let me know about it at the very last minute."I'm just hoping that it doesn't cost me a fortune!"The 'Dancing on the Ceiling' singer insists he will always support Nicole and just wants her to be happy. He said: "I told her, 'Just enjoy the ride and take your time. Whatever you want to do, just make sure it's the right decision, make the decision and roll with it.'"If that does happen, you have a husband now and you have a baby now, so wherever that goes, it's going to be wonderful."Nicole is currently facing DUI (driving under the influence) charges following her arrest last December, after driving the wrong way on a California highway. Her trial date is set for July 11 and if found guilty, Nicole faces a minimum of five days in jail.
