Celebrity Net Worth notes that Nicky is an heiress to the 100-year-old hotel empire, although 97 percent of the family fortune was donated to charity upon her father's death, leaving the rest to be divided between his children. Through her marriage to James Rothschild, of the elite family whose wealth is so vast the extent of it isn't even known (they were considered to have held the largest private fortune in the world during the 19th century), Nicky is even better connected money-wise.
The Rothschilds remain involved in lucrative businesses, including banking and mining, with their estimated net worth somewhere between $400 billion and $1 trillion. Nicky, meanwhile, began her career as a fashion designer after completing her degree in 2004. She's gone from strength to strength ever since, whether collaborating with eLuxe, Linea Pelle, and Smashbox cosmetics, or penning a style tome, 365 Style. In 2019, the heiress released her first-ever shoe collection.
