The Hills star debuted her 'mini bump' on the photo-sharing app just weeks ago, but now Audrina has snapped her growing tum once again as it begins to pop.
Still sporting a neat little bump, there's no doubt Audrina's stomach is getting bigger as she slowly approaches her due date.
In her photo, the reality star is stood side on for a selfie, baring her tummy for the camera. Alongside her post, she told fans: "For all of you girls asking me to show the bump here ya go!:).... Now this is a debut #selfie."
Anyone else hoping this is the start of many?
Audrina first announced she was pregnant in December last year. She is expecting her first child with fiancé Corey Bohan and to announce her exciting news, the US beauty shared a blog post to her official website.
It read: "I have some AMAZING news to share with you all! It has been incredibly difficult keeping my mouth shut on this one because all I've wanted to do is shout it from the rooftops!
"But, now that my doctor has given me the OK, it is safe to announce that…. I'm PREGGERS!!!:)."
Audrina added: "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.
"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!"
Audrina and Corey's baby joy comes just a month after the couple revealed they are now engaged.
