The first time she saw her on screen, Jazmin Grace Grimaldi knew she had a connection with her grandmother, Hollywood icon Grace Kelly. "One of my first and fondest memories involving my grandmother was watching 'High Society,'" the 23-year-old told Harper's Bazaar of seeing Kelly in the 1956 film for the first time. "It was a real goose-bumps moment for me."

For much of her life, it was a secret from the world that Grimaldi was royalty. Kelly famously wed the prince of Monaco, Rainer III, in 1956. Her granddaughter Grimaldi lived out of the spotlight until her father, Prince Albert II of Monaco, formally acknowledged her as his daughter in 2006. Now, Grimaldi is speaking about her relationship with her father and her admiration for Kelly, who died following a car crash in 1982, for the first time in the August issue of Harper's Bazaar . Michael Avedon photographed Kelly for the issue. His late grandfather Richard Avedon shot Princess Grace for Vogue in 1971 .
