They are the glamorous cousins of Prince William and Prince Harry, who often show off their enviable jet-setting lifestyles on social media.
And Lady Amelia and Lady Eliza Spencer have been celebrating their 31st birthday in style after sharing photos of their sun-soaked South of France holiday. The model twins, who are daughters of Princess Diana's brother Earl Spencer, spent their big day with their partners at the luxury five-star Hôtel Cap-Estel on the Cote d'Azur.
Sharing a glimpse into how she spent her birthday, Amelia shared a photo of herself and husband Greg Mallet enjoying a swim in the sea and a paddle session, noting it had been a "dream birthday morning".
Paying tribute to his wife, Greg also shared a loved-up snap from the holiday and wrote: "Being able to love you (and to be loved back) is the greatest gift I could have ever asked for."
Meanwhile, Eliza's partner Channing Millerd also posted a stunning snap of him hugging his girlfriend with the caption: "'Happy birthday to the love of my life, my rock and my world. Thank you for making every second of every day the biggest adventure."
The twins are from their father's first marriage to Victoria Lockwood and also have an older sister Lady Kitty Spencer and a younger Louis Spencer, who has the title, Viscount Althorp.
Amelia and twin Eliza, who are both models, were born in 1992, grew up in South Africa and were just five when their late aunt Diana died.
In 2021, they gave a rare joint interview to Tatler where they shared fond memories of their "incredibly warm, maternal and loving" aunt. Speaking about Diana's death in 1997, Eliza said: "As a child, I realised the enormity of the loss for my father and family. It was only later that I came to understand the significance of the loss of her as a figure in the world."
Earlier this year, Amelia - who has been dubbed the 'most beautiful' royal - married her husband Greg in a mountain-top wedding in Cape Town, South Africa. Among the family members joining Amelia on her big day were Eliza, Kitty and her younger half-brother Samuel Aitken. But her dad Earl Spencer was there.
William and Harry were not mentioned as attending the nuptials either, with the Court Circular showing William holding a meeting in his role as president of the Earthshot Prize that day.
Amelia did attend William's wedding to Kate at Westminster Abbey with her sisters in 2011, although she was curiously missing when Harry tied the knot to Meghan Markle in 2018.
The wedding came just over a year after older sister Kitty, 32, hit the headlines in July when she married wealthy businessman Michael Lewis, 64, in a stunning three-day wedding in Italy.
She wore a series of gowns by Dolce & Gabbana with her main dress, which had an intricate floral lace design, a high neck, long sleeves and puffed shoulders, reportedly taking six months to create.
