Earl Spencer's daughter, who is cousin to Princes William and Harry, looked sensational in a red two-piece barely-there bikini which had gold piping and string ties as the sides.

Wearing her trademark golden blonde wavy tresses tied back from her face, the sexy socialite finished off her day on the beach ensemble with a pair of oversized shades.

The young royal, who grew up in South Africa with her mother, Victoria Lockwood, a former model and Earl Spencer's first wife, was looking more curvaceous than usual as she enjoyed her extended trip in the Australian city.

Fast becoming a showbiz circuit favourite, Lady Kitty was joined by Tobin on the sand.

Looking at ease in each other's company, the shirtless hunk joined the pretty heiress on the beach wearing blue Bermuda shorts and dark aviator-style shades.

At one point the new friends strolled along the shoreline before enjoying a dip in the ocean.

The pair were later spotted eating lunch together, where Lady Kitty sported a matching red kaftan over her bikini.

Lady Kitty has reportedly been dating Niccolo Barattieri di San Pietro, 44, since June of this year. Their current relationship status is unknown.

But the property tycoon, who is 20 years her senior and has three children with his first wife, was nowhere to be seen, and is not believed to have joined Kitty during her three-week trip.

Australian gossip magazine New Idea has claimed that Kitty and James may be romantically involved, quoting a source who allegedly said: 'It's early days, but they're crazy about each other.

'James love's Kitty's sharp wit and bubbly personality, and also that she's not a stick insect like so many women he meets'. 

Lady Kitty has become something of a regular on the international jet-setting scene and has been photographed with the likes of Nicki Minaj and attending premieres.

She had originally jetted out to Oz to enjoy the Melbourne Cup and the racing season and she thoroughly enjoyed her time at the races.

She explained: 'It was so much fun, it was really incredible. I knew it was a big spectacle and a fabulous event but it was such a positive experience.'

And it seems the you royal is not exactly in a hurry to return to London as she gushed about how much she was enjoying her first time in Australia.
