Audrina Patridge's very first appearance on "The Hills" featured the brunette beauty sporting a bikini at the Hillside Villas with pals Lauren Conrad and Heidi Montag. Fast forward 10 years, and the MTV alum is introducing her kiddo-on-the-way in her trademark swimwear.

"Burrito or baby?" the 30-year-old, who excitedly revealed that she was expecting a baby with fiancé Corey Bohan last month, captioned the Instagram image above. "@bowie82 posted this debut of my mini bump so figured I should toooo," she added of the beachy snap, which was taken in the BMX rider's native Australia.

We would say it looks more like a human instead of the delicious Mexican dish -- but that's just our opinion. As for the parent-to-be, how is she feeling now that she's avec child?

"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!" Audrina revealed on her website shortly after announcing her life-changing news.

And will the longtime couple be seeing blue or pink? Even the future mom and dad don't know...

"Finding out the sex of the baby…we just want it to be healthy," she divulged. "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!"
