Tammy Hembrow recently raised eyebrows when she debuted her slender postpartum figure just days after giving birth.

On Saturday, the fitness influencer, 28, marked four weeks since giving birth to her third child by flaunting her slim physique in a bikini.

In a series of images shared to Instagram, Tammy showcased her muscles in the green swimwear, which put her muscular form on display.

Holding her arms above her head, she worked her best angles and flexed her flat tummy. 

'Homebody. Four weeks Postpartum,' Tammy, who had on glamorous makeup and nude lipstick in the photos, wrote in the caption.

Many fans praised the businesswoman for her 'real' and 'raw' photos.

It comes after comedian Celeste Barber criticised Tammy for showing off her toned body just 12 days after she gave birth.

In an Instagram post on June 30, Tammy revealed her slim and toned body in activewear just 12 days postpartum, saying she stayed as active as possible during and after her pregnancy. 

The social media star went on to emphasise that everyone's journey is different and people shouldn't compare themselves to others.

'That being said I work and have worked extremely hard and want nothing more than to motivate and inspire you!' she added. 

Celeste later reposted Tammy's video and wrote: 'No disrespect, well done on your success but this is dangerous. 

'Women should NEVER feel as though they need to put on activewear and show off their bodies to prove a point, ESPECIALLY 12 days after having a baby. 12 DAYS!'

Celeste, who shares two young sons with her husband Api Robin, then shared her own experience just days after giving birth. 

'Jeez I was s**ting in a bag and screaming into a pillow after having my babies. How we look is irrelevant,' she said. 'Be kind to yourselves, moisturise your nipples and unfollow accounts that make you feel like s**t!' 

Tammy welcomed daughter Posy last month with her Ironman fiancé Matt Poole. 

She is also mother to son Wolf, six, and daughter Saskia, five, from a previous relationship.
