Former The Hills star Holly Montag is preparing for motherhood just four months after getting married.
It appears the reality star told her family about the baby news over Christmas (14) and her sister Heidi just had to tell everyone.
She tweeted, "Couldn't be happier for my sister @hollymontag Christmas miracle!!!!! Love you!!!"
Heidi's post linked to a photo of the newlyweds posing by a Christmas tree. In the shot, a smiling Holly cups her bulging baby belly.
Holly, 31, wed Richie Wilson in Colorado in September (14).
And it seems her little sister, 28, won't be too far behind - Heidi revealed she was desperate to become a mom last year (14), stating, "(Husband) Spencer (Pratt) promised me a baby by 29. Last year (13), while we filmed an E! (TV) special, he told me, 'I don't want to have kids', and I started crying. I told him I couldn't bear the thought of never becoming a mom. So when he saw how important it was to me, he had a change of heart!"
