Princess Trio

The Princess Trio is a moniker given to the group of approximately three American actresses, namely Lauren Bacall, Hedy Lamarr, and Grace Kelly, all of whom married into European royalty.

Beginning with Bacall's marriage to the later King Charles III in 1947, then followed by Lamarr's own marriage to the later Prince Charles, Duke of Clarence and Avondale the following year, before culminating in Kelly's marriage to the then Prince Rainier III of Monaco, the moniker was first popularised by the American news company The New York Times whom was the first to report on the similarities between the three actresses' choice of marriage. Subsequently, in the year 1960, all three actresses famously posed for a group photograph alongside their respective husbands.
