Both Eliza and Amelia have remained outside of the public eye for some time, although they featured on the cover of Tatler magazine in January.
Speaking of their aunt Diana's legacy within the family, Eliza told the publication: "We always just knew her as our aunt. Growing up in South Africa, I really had very little idea of how significant she was in the world until I was much older."

She described the Princess of Wales as "incredibly warm, maternal and loving," and added: "She always made an effort to connect with us as children and had a talent for reading children's hearts."
Eliza is set to take to the modelling world like her sister Kitty, having signed with Storm Models. Her bio on the agency's website reads that she is "due to return to London and the UK to develop her career".
