Instagram model looks unrecognisable in high school flashback photo

Guess who! She’s known for her VERY raunchy fashion sense these days – but can you recognise this celebrity as a high school student?

She’s the Australian model and businesswoman known around the world for her sensational figure.

And on Friday, this 26-year-old entrepreneur shared a rare throwback photo to Instagram from her high school days.

In the picture, she blew a kiss to a school friend as they posed in their school uniforms – but can you guess who it is?

Guess who! She’s known for her VERY raunchy fashion sense these days – but can you recognise this Australian celebrity (right) as a high school student? 

The schoolgirl in the photo is none other than health and fitness mogul Tammy Hembrow. 

She uploaded the post to celebrate the birthday of her friend, Isabelle Laws, who was the other girl in the image. 

Isabelle now works as the General Manager for Tammy’s popular sportswear brand, Saski Collection.

Tammy also posted another, more recent, photo of herself with the birthday girl and explained in the caption they had been friends since high school.

She wrote: ‘Happy birthday to one of my favourite humans! I’ve literally known her since grade nine of school. Love you forever.’

Tammy’s birthday tribute to her friend comes after she shared perhaps her most risqué Instagram post yet.

This mother of two flaunted her trim and toned physique in an incredibly tiny rainbow bikini. 

In a gallery of raunchy photos, Tammy struggled to contain her ample cleavage and plump derrière in the flimsy swimwear. 

Her bikini featured G-string bottoms and a triangle top, which she tied around her back instead of over her shoulders.
