Billionaires Fiancée Wows in Bikini on Superyacht

and his fiancée Kylie Lim have joined the rich and famous to enjoy a European summer in Sardinia, .

Packer and Lim are cruising the Mediterranean on the billionaire mogul's $200 million superyacht and were spotted entertaining a group of their friends on Wednesday.

Lim showed off her incredible figure in a designer snakeskin bikini as she soaked up the sunshine on the deck.

Meanwhile, Packer, 58, covered up from the sun in an oversized navy blue t-shirt and matching trousers.

He appeared to be mixing business with pleasure, with real-time financial market coverage on American channel CNBC playing behind him on a giant TV screen as he chatted to his male pals.

Meanwhile, Lim looked keen to work on her tan in her tiny two-piece, which she accessorised with her giant engagement ring, estimated to be worth $1.2 million.

She also wore other jewels, including a giant diamond cross and gold and diamond bracelets.

Lim revealed her natural beauty by going make-up-free and sported a fresh French manicure.

The vessel, named IJE after Packer's three children with Erica Packer– Indigo, Jackson and Emmanuelle – has become something of a floating retreat for the billionaire in recent years.

On this trip, Packer and Lim hosted a close-knit group of friends, including Yolanda Hadid's long-time best friend, Paige Larkin.

Lim recently offered an extraordinarily rare glimpse into her international friendship circle after photos surfaced from her yacht holiday in Turkey.

The images, taken during a Mediterranean getaway in August last year, show the bikini-clad former model enjoying a sun-soaked escape with a group of wealthy jet-setters.

Among those joining her was Francesca Versace, the niece of designer Gianni Versace and daughter of Santo Versace, the former CEO of the Italian fashion house.

Francesca is part of one of fashion's most recognisable dynasties and has remained closely connected to the luxury world through her family name.

While she maintains a relatively private profile, she is a familiar face within Europe's elite fashion and society circles.

Lim was also pictured spending time with Berna Uyanoglu Meehan, a Turkish businesswoman and philanthropist who is a regular fixture on the Mediterranean social scene.

Berna, who is married to businessman Patrick Meehan Jr, is known for her connections across Turkey, Europe and the United States.

The couple is often seen at high-end events and among the international jet set, with Patrick also joining the yacht holiday.

Lim, Francesca and Berna were also photographed together at Scorpios Bodrum, one of Turkey's most exclusive beach clubs.

Another friend within Lim's wider circle is Bella Hunter Friedman, a New York- Australian socialite and musician who is married to American furniture entrepreneur Gary Friedman.

Bella, like Lim, is no stranger to the high life, often attending VIP parties and fashion shows on the arm of her mega-wealthy partner.

Italian publicist and content creator Lulu Buti is another glamorous woman who calls Lim her close friend.

Lulu spends her days working and travelling the world, making sure to share her enviable wardrobe on social media.

Other friends of Lim include American real estate agent Ariane Benjamin, NBA-player-turned-DJ Rony Seikaly and MasterChef Australia star and socialite Michelle Walsh.

Michelle is the owner of high-end event planning company Luxe Attaché and is married to Chadwick Models owner Martin Walsh.

Like Lim, she spends plenty of time holidaying at luxurious destinations and attending exclusive parties.

Lim herself has long been accustomed to life among the global elite.

Born in Canada, she began her career as a model before becoming a fixture in New York's social scene, where she built connections across the worlds of fashion, entertainment and business.

Her relationship with Packer, one of Australia's most prominent billionaires, has further

Packer announced the couple's engagement earlier this year after reports emerged that Lim had been seen wearing a diamond ring while running errands in Aspen, Colorado.

'We are very happy to be engaged and looking forward to the future,' Lim told news.com.au from Los Angeles in March.

The couple were together for almost three years from late 2017 to 2020 before rekindling their romance last year.

Packer was previously

He married Meares and Baxter, with whom he had three children.

Packer previously credited Lim with helping him through a dark period of his life following his messy split with Carey in 2016 and battle with substance abuse.

'Kylie has been a wonderful influence on my life. I love her very much,' he previously told the Sydney Morning Herald.

No date has been confirmed for the planned wedding.
