In the sizzling snap, which she shared with her 76,700 followers earlier today, the BBC star showcased her incredible dancer’s body in a stylish miss-match bikini.
The former World champion dancer wowed in a strapless floral top and eye-catching purple bottoms, which showed off her toned body.
Her washboard abs were on full display in the bold bikini bottoms, which featured a cutaway detail at the hip and also had a pretty bow which tied at the side.
Nadiya tagged her location as Croatia as captioned the snap: “Vacation calories don’t count”.
The beautiful blonde, who was partnered with former footballer David James in the most recent series of the BBC ballroom dancing competition, wore her hair loose for the photograph as she relaxed in the sunshine by the sea.
She could be seen laying on a boulder on the stony beach with the ocean and a cloudless sky in the background.
One hand rested by her face as she struck a pose for the camera.
The mum-of-one, who shares four-year-old daughter Mila with her partner Matija Skarabot, was clearly making the most of the warm weather on her vacation.
Instagram users and fans took to the comments section to share their thoughts, with many simply posting a fire emoji.
One user wrote: “Wow you are stunning Nadiya,” alongside the sun-soaked picture.
Another added: “Omg, what a beauty,” while a third fan said: “Breathtaking.”
The social media snap was also liked by fellow Strictly stars – past and present – Brendan Cole, Dev and Johannes Radebe.
