We may remember her as the brunette, rock chick from The Hills who spent much of her on screen time pining over bad boy Justin Bobby, but Audrina is officially all grown up.
The reality star has just announced that she is expecting her first child with her fiancé, Corey Bohan.
The 30-year-old star just announced the happy news via her Instagram, posting a sweet snap which gave the game away.
"I finally figured out what to get Corey for Christmas! #babyontheway," read the caption.
Audrina's BMX biker boyfriend popped the question just last month after several years of on-off dating between the pair. You may recognise Corey from his various cameos on the Hills over its six season run.
The reality star said she plans to share all of her pregnancy updates with fans on her blog, The Inside Out.
First Kristin Cavallari, now Audrina… our money's on a mini Lauren next.
