"I'm loving it," he gushed to us recently at the March of Dimes Celebration of Babies luncheon in Beverly Hills. "I'm loving it. I look forward to many more. I can't wait for him to tear through gifts. It won't be this year."
As for his plans for his first Christmas as a dad, the 41-year-old actor gushed to E! News, "Our Christmas plans are pretty simple this year. I like it that way. We're home, just family around here. My mother's out here right now. My sister's coming out next week. Other than that we're just going to stick around here."
It sounds like Duhamel may have many more Christmases to come with more than one child. When E! News asked Fergie if she wants a little girl this week, she gushed, "Of course, that would be amazing."
Meanwhile, Duhamel dished about why it's important for him to support March of Dimes, which helps parents struggling with problems affecting pregnancy and premature babies.
"I don't really feel proud of the fact that I'm admitting this, but it isn't until you have a child that you really can understand what some parents must go through who aren't fortunate enough to be blessed with a completely healthy child," the new dad said. "We luckily were and it's a chance for me to help in some way, some small way, those who are struggling to raise a child with special needs."
