Tammy Hembrow showed off her natural curves in a G-string on Monday, in a racy snap.
The 25-year-old showcased her impossibly toned backside while posing at the beach in a very skimpy blue and white bikini.
'Get your mind right', she wrote in the caption.
Tammy's latest selfie comes after trolls accused the Fitness guru of having 'butt implants' earlier this year.
However, the mother-of-two insisted that her body is 'all natural' and that her physique is the result of a strict diet and gruelling exercise routine.
Taking to Instagram in August, the busty blonde opened up about her booty transformation experience.
'Anyone who knows me well knows that I've been up and down with my weight my entire life,' she wrote alongside very risqué before-and-after photos.
Tammy showed off her noticeably flatter posterior in the before shot from 2014, in which she wore a pair of white bikini bottoms. (Mon 9)
