Their recent regular hangouts on the Gold Coast have sparked rumours of a romance.

And on Friday, speculation went into overdrive as Married At First Sight stars Tamara Joy, 29, and Ivan Sarakula, 31, cuddled up for a sexy beach selfie - wearing nothing but skimpy swimwear as they soaked up the Queensland sun.

However, despite the allure of a reality romance, the pair have both exclusively revealed to Daily Mail Australia that they are nothing more than  'just friends' - with no wiggle room for anything romantic in future.

Rumours first began to swirl when the duo spent the festive season together, and posed in very sexy ensembles by the tree.

Ivan's costume consisted of a pair of underwear with the face of Santa placed in rather racy position, and a pair of red straps that ran up his chest.

He also showed off her new, long hair in the image, and held Santa's hat up against his torso in a suggestive manner as he beamed for the camera.

Tamara meanwhile looked adorable in a Mrs Claus outfit that flaunted her impressive physique.

He captioned the photo simply 'Merry Christmas' then joked on Instagram Stories that the pair had picked matching outfits by accident.

Ivan has been in the sunshine state spending time with his former co-stars including Tamara and Hayley Vernon.

In recent months, Ivan has drastically changed his appearance by growing out his hair and hitting the gym to add some muscle to his frame.

He's also changed his fashion sense, swapping his usual dress shirts and trousers for tank tops and ripped jeans.

Ivan was partnered with fellow real estate agent Aleks Markovic on Married At First Sight earlier last year, but they are no longer together.

Meanwhile, Tamara rose to fame on the sixth season of the show, and 'tied the knot' with Dan Webb - who continued on the show with new flame Jessika Power.

The pair's short-lived romance failed to last away from the show.
