"Was your nose before getting it done a big insecurity. What age did you get it done?", wrote the fan.
In response to the fan's question, the 30-year-old MAFS star shared a throwback pic of herself to declare she went under the knife at the tender age of 22.
"This is me before my nose job, I was 22 when I got it done," wrote Martha.
Perhaps the most surprising revelation is that the Kim Kardashian lookalike seems to ever so slightly regret the procedure, writing, "Still cute" under the caption.
Earlier this year, Married At First Sight's Martha and her TV 'hubby' Michael, both admitted to having nose jobs.
As well as her nose, Martha has been open about enhancing her boobs with breast implants and tightening her face with botox, with a reality TV makeover not too dissimilar to co-star Jessika Powers.
Whilst we prefer the natural look, at the end of the day it's whatever makes you happy!
