"What's better than winning an Oscar?" asked Joel Madden, Good Charlotte frontman and boyfriend to Nicole Richie. The answer? Baby number two for the celebrity couple. According to the rocker, Baby Harlow "is going to be a big sister."

In an entry on Good Charlotte's official blog, Madden revealed the news, saying "I am so happy to tell everyone that Harlow is going to be a big sister! God has truly blessed my family. Hope you're all feeling as good as I am right now."

Nicole Richie's life "reads like a train wreck," according to her father Lionel. The 59-year-old singer - who is Nicole's adoptive dad - admits he was "worried" about his daughter when she was arrested for driving under the influence of marijuana and painkiller Vicodin in 2006, but is delighted with how she has turned her life around.

He said: "I was worried about her. I mean, her life story reads like a train wreck, but she has amazing powers of recovery. She went through her drug period, then came back to center. She went through a car accident, then came back to center.
