Martha Kalifatidis sent fans into a frenzy on Wednesday after a confusing social media post had them questioning if she was expecting another baby.

The former Married At First Sight star, 37, gave her Instagram followers a sneak peek of a fashion event she attended last week.

The dinner, which was hosted by Aussie brand VRG GRL, welcomed the likes of celebrity hair guru Gabrielle Roccuzzo, stylist Jess Pecoraro and content creator Emily Yates.

Martha, who already shares son Lucius with fiancé Michael Brunelli, stunned in a bright red button-up top, which she stylishly paired with baggy jeans, blue strappy heels and chunky Anna Rossi bangles on her arms.

In the photo dump, the reality star shared pictures of the dimly lit restaurant, bowls of ravioli pasta and her glamorous friends – as well as a photo of a pregnant belly dressed in the same red cardigan.

Fans of the MAFS star flooded the comments section to point out the picture, speculating whether the photo was of Martha and if she was in fact pregnant.

‘Who else ran straight to the comments to see if they saw what they think they saw….’ one person wrote of the suggestive snap.

‘Congrats if you’re preggas…’ one fan sweetly wrote, while another penned: ‘The baby is coming.’

Another sent Martha well-wishes, writing: ‘Queen you’re so brave and wish you all the besssssst with this pregnancy.’

‘Did I just see a ‘bump’,’ another asked.

It didn’t take long for one fan to figure out that the belly didn’t belong to Martha, but rather her friend and influencer Oriwa LeFevre, who wore the same top on the night out.

‘It’s @oriwa everyone, you nearly got us Martha,’ the fan wrote.

This isn’t the first time pregnancy rumours have swirled around the social media personality.

In January, Martha addressed rumours she is expecting her second child in an Instagram post, giving her fans a glimpse at her idyllic vacation in Thailand with fiancé Michael Brunelli and the couple’s young son, Lucius.

In the caption, she told her fans she’d been offline as she was on holiday, after going two weeks without posting to Instagram.

‘Hi everyone. I’m not pregnant (thanks for asking though),’ she wrote in her caption alongside the series of images.

‘I was just having some time off in Thailand. It was swell, missed you all,’ she continued.

In the photos, Martha showed off her figure in a black swimsuit as she enjoyed a soak with her toddler.

She also kicked back on a boat, as well as working her angles in the shallows of the turquoise ocean.
