Itty bitty bump! Audrina Patridge, who's currently pregnant with her first baby, posted a photo of herself baring her growing bump in a bikini on Wednesday, January 20.

"Burrito or baby?" the MTV Hills alum, 30, joked on Instagram, alongside the snap of herself knee-deep in the water and looking down at her tummy.

Patridge told fans that the baby's father and her fiancé, Corey Bohan, was first to share the picture, which prompted her to do the same. "@bowie82 posted this debut of my mini bump so figured I should toooo," she noted.

The former reality star confirmed the news of her pregnancy to Us Weekly last month, and said she was "superexcited" after seeing the results of the pregnancy test. "I asked [Corey] to have a look at the test and make sure I wasn’t seeing things!" she told Us of her reaction. "You never really expect it to say 'pregnant.' He had a big smirk on his face and was really happy about it."

While the news was a surprise, Patridge — who got engaged to Bohan in November — said she's ready to nurture a little one. "I feel, at this point in my life, I am ready to be a mama!" she gushed to Us.

There are, of course, perks to being pregnant. "So far, my bra has just gone up a size!" she told Us. "I still work out and go about my normal routine. I just get tired easily."
