The eccentric Duchess — whose full name is Maria del Rosario Cayetana Alfonsa Victoria Eugenia Francisca Fitz-James Stuart y de Silva — goes by Cayetana. She is a distant relative of Queen Elizabeth and Winston Churchill. She's worth between $800 million and $4.7 billion, depending on whom you ask. The groom is a 60-year-old civil servant named Alfonso Díez, but as you can see in the clip above, all eyes were on the bride, who wore a soft pink dress and did a little flamenco on the red carpet outside her 15th century palace in Sevilla after the ceremony. Skip ahead to the :48 second mark to see her moves.
