Joel Madden has said he'll marry Nicole Richie

'Good Charlotte' rocker Joel Madden has said that he'll marry the mother of his unborn child, socialite Nicole Richie.

According to People.com, the "Lifestyles of the Rich and Famous" rocker said: "Obviously, marriage is in our future," Madden told Ryan Seacrest on his KIIS-FM radio show Tuesday. "I don't know when or where or how, but right now our priority is our family and is the baby."

The singer added: "That's all we've been thinking about. We are in love and are really happy."

25 year-old 'Simple Life' star Nicole Richie, and 28 year-old rocker Joel Madden confirmed the pregnancy on TV show Good Morning America in late July: "Yes I am. We are. I'm almost four months," Richie told the show's Diane Sawyer. The couple has been dating since earlier this year.
