However, the brunette bombshell 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 sexy video on Instagram.
Posing provocatively and spinning around in a pair of light grey bike pants, Martha lifted up her white T-shirt to show off her fake, tanned tummy and toned butt.
She captioned the video, ‘Haters will say it’s photoshopped’ with a waving emoji to silence those who accuse her of editing her selfies.
And it’s not the first time the star has been forced had to defend herself against eagle-eyed fans.
Recently, critics accused Martha of altering another photo from her Greek islands holiday.
On August 6, Martha 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 vehemently denied 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.
