Audrina Patridge has announced on Instagram that she’s expecting with her first child with fiancé Corey Bohan.

The former Hills star, 30, just announed her engagement to the BMX pro late last month.

"I finally figured out what to get Corey for Christmas!” she wrote on Instagram, along with a photo of herself holding a positive pregnancy test. “#babyontheway #ClearblueConfirmed.”

She also spoke to Us Weekly about finding out about the surprise pregnancy, saying she asked Bohan to look at the test to make sure she wasn’t “seeing things.”

"I feel at this point in my life I am ready to be a mama!" she said.
