Hilary Duff will welcome her first child, a baby boy, with husband Mike Comrie early next year. The singer and actress, who is four months along, is already well into planning for the arrival of her bundle of joy. The 24-year-old already has baby names picked out, but shes waiting for delivery day to decide on the name.

"We have one that's very traditional and one that's more unique, and when the baby comes out, we'll decide then," Duff told E! Online. She says, though, the unique name isnt too crazy. "It's not a fruit or a veggie," she joked.

Whether Duff decides to be traditional or not, she plans to have more than one baby, so maybe shell use the other name when she further expands her family. She says the reasoning for a desire of a big family comes from the closeness she has with her sister, and the large family her husband comes from.

"We definitely want to have more than one," she continued to tell E! Online. "We don't want to have just an only child. [Mike] comes from a large family. I'm super close with my sister. I think that's important. But we are not planning that right now. We're like, 'Let's see how one baby goes.' "
