Speaking to US Weekly, Audrina said: "I was super-excited. I asked [Corey] 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!"

The couple became engaged two months ago, with Corey proposing over dinner at Summit House in Orange County, California. Sharing details of the night Audrina said: "When dessert time came he ordered cheesecake and the waiter brought it out on a platter with a beautiful silver cover. 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. It was then that Corey dropped to his knee and 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!” Corey is also said to have asked Audrina’s father for permission before proposing to her.
