Kim, now 33, got the chance to tell Elizabeth she was her idol in person and even ask for beauty, glamour and life tips—including "advice on how to be a queen" like Cleopatra, the Egyptian queen the actress portrayed in 1963.

"I have never wanted to be a queen! Cleopatra was a role, and I am an actor, so it was fun to play one, but it's not real," Elizabeth explained. "The real Cleopatra had an incredibly complicated life, and she had to be very, very canny to survive as long as she did. For me, the most interesting thing about her was her passion. The things that are important to me—being a mother, a businesswoman, an activist—are all things that were borne out of great passion."
