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".
