On August 6, the former makeup artist was pictured posing in a pale pink bikini on a hotel balcony in Mykonos, and captioned the photo, "It's not often I post a photo without a filter but when I do."
While she was adamant that the photo was unfiltered, the warped edges and blurred sections of the image raised suspicion amongst her followers.
"But when you do, you post it with a bit of a nip and tuck with a liquifying app," wrote one follower, noting the blurred areas underneath Martha's left armpit and upper arm - both of which appeared to blend almost completely into the background.
Married at First Sight's Martha Kalifatidis has reportedly been hit with a $3650 phone bill while holidaying in Greece.
However, the brunette bombshell has since silenced her haters by reportedly telling news.com.au that she doesn’t "give a f**k what people think of me."
She also hit back at critics by sharing a provocative video on Instagram.
Posing seductively in a pair of light grey bike pants, Martha lifted up her white T-shirt to show off her fake, tanned and toned body.
She captioned the video, ‘Haters will say it’s photoshopped’ with a waving emoji to silence those who accuse her of editing her selfies.
Her MAFS co-star and boyfriend Michael Brunelli also offered support to his MAFS bride during the backlash.
The reality star shared one of Martha's bikini photos to his own Instagram page and photo-shopped himself onto it, writing: 'Haters will say it's shopped, but we just out here killin' it in Greece #nofilter.'
