Pregnant Audrina Patridge shows off Her ''small baby bump'' in a Bikini

The pregnant Hills alum is taking a break from the cold, California winter and soaking up some sunshine and vitamin D while vacationing in Australia with her fiancé, Corey Bohan.
Both took to Instagram to share the same photo of Audrina hanging out on the beach showing off her bump, in a two-piece black and turquoise bikini.
"Burrito or baby?" Audrina re-posted the photo from Corey. "@bowie82 posted this debut of my mini bump so figured I should too.

The couple first announced their pregnancy mid-December, and although they admitted it was a bit of a surprise, they're incredibly excited to welcome the new addition to their family!
