Prince Charles & Princess Diana – Estimated $135 Million

Everybody loves tuning into the Royal couples’ grand ceremonies, and Prince Charles’s special day with the late Princess Diana was indeed one for the books. Sources say their nuptials cost a whopping $135 million, and over 750 million people worldwide watched the televised ceremony.

Despite how perfect they looked that day, their marriage had many problems, and they both cheated on each other. They ended their marriage in 1996, and Princess Diana sadly died a year later. Prince Charles is now married to Camila Parker Bowels, and he will claim the throne once Queen Elizabeth II passes away.
