Who: Emmy and Golden Globe-nominated actor Rob Lowe, 55, and Princess Stephanie of Monaco, 55.

How They Met: In 1983, Lowe arrived in London to film Oxford Blues. According to his 2011 memoir, Stories I Only Tell My Friends: An Autobiography, Lowe suggested Princess Stephanie, whom he admittedly had a crush on, play opposite him. He never heard back. A few years later, Lowe’s friend and colleague Glenn Souham noticed the actor admiring the princess’s 1986 Vogue cover. Souham, whose security company provided for the Grimaldi family, offered to introduce Lowe to the young royal.
