The 31-year-old sister of Heidi Montag confirmed over Christmas that she is expecting her first child with husband Richie Wilson – and Heidi is thrilled!
After news of Holly's pregnancy was confirmed, Heidi tweeted: "Couldn't be happier for my sister Holly Montag. Christmas miracle!!!! Love you!!!"
Holly's pregnancy tops a very happy year for the former reality star, who wed boyfriend Richie in a fairytale ceremony in her Colorado hometown in September.
At the time, Heidi, 28, tweeted: "Congratulations to @hollymontag !! Yesterday was the most beautiful wedding I could imagine! Wishing you all the blessings and joy! Love you!"
Holly and Richie became engaged in October 2013.
Congrats to the parents-to-be!
Meanwhile, there could be another Montag baby on the horizon in the near future as Heidi recently hinted she and husband Spencer Pratt are ready to start a family.
Back in November, the 28-year-old posted a photo of Clearblue Ovulation Test Sticks to Instagram, suggesting she and Spencer are trying for a baby.
Heidi and Spencer married back in 2009 in a ceremony that was televised on The Hills.
