"I wake up in the mornings and I don't look pregnant, but the moment I eat my tummy bloats and by night I am SO bloated. It looks like a baby bump but it's actually not. Maybe all the carbs I'm eating?!" she previously penned.
The following day, she posted a second snap - her bloating mysteriously vanished.
“See! Now it’s morning all the bloating is gone!” she wrote. “Crazy! This is common though apparently.”
In her latest post on IG Stories, however, there’s no denying her bump.
“Tiny, tiny little pop!” she captioned the mirror selfie, in which she could be seen posing in a Bonds crop top, her swollen belly visible over her white maxi skirt.
In October, Tara revealed her happy baby news via an Instagram video which featured the parents-to-be sitting on a beach, popping a bottle of champagne alongside the words "baby Shep due May 2021."
"Well, at least one of us was able to enjoy some celebration drinks on our honeymoon...," Tara explained, making light of the fact she was pregnant on their wedding a few weeks earlier.
Three years ago, Tara Pavlovic scored third place behind Elise Stacy and winner Laura Byrnes in the running for Matty J's heart. She then went on to appear on Bachelor in Paradise, where her co-star Sam Cochrane famously proposed in the finale episode.
The couple went through a messy public split in August 2018, and just two weeks later Tara and Nick began dating. The pair had known each other for more than a decade.
“Tara is so happy and says he's [Nick] absolutely amazing,” a source spilled to the Daily Mail last year when news of her new romance broke.
