There's a brand-new (tiny) lady joining The Hills clan: Audrina Patridge is having a baby girl!

The 30-year-old -- who announced she was expecting a bundle of joy with fiancé Corey Bohan last December -- will be seeing plenty of pink (and cute, petite swimwear) in the not-so-distant future.

"I'm not the best at surprises," the glowing mama-to-be revealed to Us Weekly, which broke the news of the baby's sex and shared a series of snapshots from the couple's Sugarfina candy-filled gender reveal bash. "I told my family while I was still in the ultrasound room! I had to send them pictures and videos instantly." Awwww, A!

And how did the professional BMX dirt bike rider -- who actually made his debut on the former hit series during Season 4 -- react when he found out he'll soon have a daughter?

"Corey can't wait to teach her how to surf!" Drina told the magazine. "We are so excited to meet her. She already has a personality kicking around in my belly."
