She spends countless hours at the gym in skintight activewear.
But it appears Tammy Hembrow opted to ditch the restrictions of a sports bra for a more relaxed look on Wednesday.
Making a sexy statement for her legions of Instagram fans, the 24-year-old fitness entrepreneur appeared to go braless in a bright yellow crop top and denim shorts.
Posting the sizzling photograph on the social media platform, the Gold Coast mother-of-two wrote: 'Blessed with another beautiful day'.
Striking a sultry pose in her bathroom, Tammy appeared to playfully bite her finger as she flaunted her taut stomach and toned legs.
The Saski Collection founder styled her blonde tresses in a half-up-half-down 'do and opted for a natural makeup look while in her bathroom.
Tammy has over nine million followers on Instagram, including members of the Kardashian family, who regularly heap praise on her sexy selfies.
The model rose to fame in 2014 after sharing incredible photos of her post-baby body, just two months after giving birth.
She went on to build a lucrative fitness empire, which includes her workout app Tammy Fit and activewear label Saski Collection.
Tammy is believed to be worth at least $3 million, with reported earnings for Saski reaching over $3.6 million in just 12 months, according to a representative.
In August last year, Tammy made international headlines after collapsing at Kylie Jenner's 21st birthday party in Los Angeles.
Tammy has two children, son Wolf, four, and daughter Saski, two - who she welcomed into the world with ex-fiance Reece Hawkins.
