Lady Kitty Spencer – $100 million
Lady Kitty Spencer, Princess Diana’s niece, had worked very hard to increase her pay. Although she was not a member of the royal family’s main line, she had a higher income than her other well-known relatives. It was because she began with a strong foundation and a heritage from her ancestors. She earned some money on the runway as well. She worked as a model for several well-known designers and companies.
