Audrina Patridge Is Pregnant! See the "Hills" Star's Excited (& Sponsored) Announcement

The former star of "The Hills" took to Instagram on Friday to share her positive pregnancy test with the world, in a post that was sponsored by the brand she used. Anything for some extra cash, right?

"I finally figured out what to get Corey for Christmas! #babyontheway #ClearblueConfirmed #ad," she captioned the photo.

"I was super excited!" she tells Us Magazine about the news. "I asked [fiance Corey Bohan] to have a look at the test and make sure I wasn't seeing things. You never really expect it to say 'Pregnant.' He had a big smirk on his face and was really happy about it."

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

The baby news comes after Audrina and her man got engaged last month. The "1st Look" host told PEOPLE that Corey asked her father about the proposal three weeks before he got down on one knee at the Summit House in Orange County, California.

"When dessert time came he ordered cheesecake and the waiter brought it out on a platter with a beautiful silver cover," she explained. "I noticed all the waitresses gathering with phones and thought, What is going on! Then all of a sudden the waiter lifted the silver cover and I saw the ring in a box with white rose petals on the plate."

That's when he dropped down to propose!

He said, "'We have been together for many years now and I love you more than anything. I want to spend the rest of my life with you – will you marry me?' I was in shock and kind of didn't even hear him but I said yes!"
