Princess Caroline & Prince Ernst August | Married Since 1999
Caroline, Princess of Hanover, is the daughter of Rainier III, Prince of Monaco, and Grace Kelly, the actress. She holds the title attached to her name due to her marriage with Prince Ernst August of Hanover. They got married in 1999, but sadly, the prince had been seen with other women a few times over the years.
However, they are still legally married even after two decades of their relationship. In 2021, the prince was jailed in Austria and made headlines for his relationship with a Spanish artist who is around 20 years his junior.
