Holly Montag struggled a bit to find her footing in Los Angeles while on "The Hills," but she seems completely prepared to embark on her next adventure: motherhood.

Holls, who married fiancé Richie Wilson in a beautiful Colorado wedding in September, is already five months pregnant! Yup, come May 2015, there will be another "Hills" baby angling to take over the world (maybe the little one can be pals with Frankie Delgado's daughter...?), which also means that Holly's sister, Heidi Montag, and Heidi's husband Spencer Pratt will serve as adoring aunt and uncle...a role Heidi is more than ready to play.

"Couldn't be happier for my sister @hollymontag Christmas miracle!!!!! Love you!!!" Heidi tweeted after news of Holly's pregnancy began to spread and a photo of her ballooning baby bump popped up across the Internet. Man, if Heidi wanted a baby before, her maternal itch must be unscratchable now. WE WANT MONTAG COUSIN PLAY DATES!
