Pregnant Vanessa Minnillo and her husband of nine months Nick Lachey can't help but count the minutes until they become parents for the very first time.

"We definitely look forward to [parenthood]," Lachey, 38, tells the new issue of Us Weekly.

"We've been pretty outspoken about having kids." Confirming their pregnancy in early March, Lachey and Minnillo, 31, aren't yet sure of the gender of their little one, but mom-to-be Minnillo is "really hoping for a boy," an insider explains.

Should a little boy join the fold, he'd grow up rooting for Cincinnati sports teams, just like his dad, who plans to move the family to Ohio once little Lachey hits toddler age.

As they enjoy the remainder of Minnillo's pregnancy, the couple is already thinking about adding another baby -- or more! -- to their brood.

"They want to have more after this one, for sure," hints the source. "They're beyond excited."
