Following in the footsteps of mom-of-two Kristin Cavallari, one of these former Hills stars is expecting her first child, with her sister confirming the news on Twitter recently.
So who's the lucky lady? Holly Montag!
Holly, who has yet to put up a post of her own announcing the news, simply retweeted that tweet to confirm it.
According to MTV, Holly tied the knot with Richie Wilson in Colorado in September, and is already five months pregnant. Perhaps Heidi will be next...if she and her husband Spencer can come to an agreement on when they want to have kids.
While Heidi has wanted to start a family for a while now, Spencer has been dragging his feet. The couple will reportedly delve into that issue and more when they appear on WETV's "Marriage Boot Camp," which premieres Jan. 9 at 9 p.m.
