Joel Madden may have gotten the milk for free, but the Good Charlotte rocker insists he'll be buying the cow as well. Joel told Ryan Seacrest that he intends to marry his pregnant girlfriend Nicole Richie.

When Madden spoke on Seacrest's radio show Tuesday, he said, "Obviously, marriage is in our future. I don't know when or where or how, but right now our priority is our family and is the baby. That's all we've been thinking about. We are in love and are really happy."

Though the pregnancy wasn't planned, Joel says he and Nicole are "really excited about it. Its the best thing that has ever happened to us. It's awesome."

Joel also said that he and Nicole do not know the sex of their baby, which is already kicking. "No, we are waiting," he told Ryan. "We don't even know. So right now it's an it. Which sounds wrong. We call it the baby. When we talk to it, it's a you."
