Big changes are ahead for The Hills star, Whitney Port and her husband Tim Rosenman – who she’s been married to for almost two years.

The two are expecting their own little bundle of joy sometime this year!

Whitney broke the news on Instagram, sharing a picture of her bare baby bump and writing a hilarious caption. “Oh hey! Just standing by the window in my underwear, with a BABY in my belly!!! ?? DM me if you know what I'm supposed to do with this thing for how ever many years I'm supposed to be in charge. Check out my blog for a little letter from me & Timmy and for more behind the scenes of this crazy journey!!!! We are sooooo excited!!!! ?: @colemoser,” she wrote.

Whitney also shared her thoughts on becoming a mother on her blog by writing, “Timmy and I were a bit shocked, but so excited to begin this journey.”

“I can’t wait to be a Mom, but the fact that there is another person inside there is seriously crazy,” she continued to write.

We couldn’t be happier for Whitney, but she’s also not the first The Hills alum to announce she’s expecting. At the beginning of the year, her old bestie Lauren Conrad announced she was expecting her first child as well, Audrina Patridge welcomed a daughter into the world last year, and we all know Kristin Cavallari is the proud mother of three children.

If Whitney needed some advice on motherhood and what’s in store, she has more than a few people she can lean on for whatever she needs. Though this also has us wondering if some time down the line, the girls will get together with their kids for another The Hills reunion.

How cute would that be?
