The Hills alum revealed the news on Instagram Friday, posting a shot of herself posing with her positive Clear Blue pregnancy test. "Finally figured out what to get Corey for Christmas! #babyontheway #ClearblueConfirmed #ad (blog post with all the details will be up today, couldn't wait to share the news with you all:)! Xoxo," she captioned the snap.
As promised, Audrina shared more details of her pregnancy on her blog, writing, "You guys don't even understand how hard this was to keep a secret, but my family and close friends did a good job of hiding the news, which made it a little bit easier."
"It started with me not feeling too well — I didn't feel sick, but I definitely knew something was off between my mood swings and lack of energy," she continued. "So, I took the test and TA-DA! I couldn't even believe my eyes. I called Corey upstairs to make sure I wasn't just seeing things and, well, let's just say that he had a permanent smile glued to his face for the rest of the night!"
The night they found out they were headed to a dinner party and Audrina told everyone she was on a detox cleanse to cover up why she wasn't drinking. "With the combination of my poor lying skills and Corey's perma-smile, we were given 'the look' over and over again by our friends and family, so it's safe to say the secret was not a secret much longer!"
"So far, I haven't had any morning sickness, I just feel very tired and like I have a major hangover when I wake up, which is a change for me because I'm constantly on-the-go!," she continued. "As far as finding out the sex of the baby...We just want it to be healthy:) Girl or boy, we will be ecstatic either way! Corey's mum wants it to be a surprise, but I don't know if I'll be able to wait! I guess we will just have to wait and see. God has a plan for us, and even though it is all happening so fast, I am confident that I'm ready to be a mama!"
This will be the first child for the 30-year-old reality star and her fiancé, professional BMX dirt bike rider Corey Bohan, who got engaged last month after dating on-and-off for seven years.
