The 85-year-old duchess of Alba and one of Spain's richest women, Cayetana Fitz-James Stuart, was married here Wednesday to a civil servant 25 years her junior.

Once again flaunting her disregard for social convention, the twice-widowed Cayetana wed Alfonso Diez, 60, before a few dozen guests in the chapel of the duchess' Seville residence, the Palacio de las Dueñas.

The couple, who were acquainted by way of Cayetana's second husband and Diez's brother, ran into each other three years ago at a Madrid cinema and later began dating.

Four of the duchess' six children were present for the nuptials.

The youngest, Eugenia, was said to be in a Madrid hospital with chicken pox. Son Jacobo pleaded an unbreakable prior commitment, but some suggested he boycotted the event to express displeasure with his portion of the family's immense wealth.

In a bid to overcome her offspring's opposition to a third marriage, Cayetana parceled out parts of her estate - estimated to be worth anywhere from 600 million euros to 3.5 billion euros ($800 million-$4.7 billion) - among the children earlier this summer.

The duchess' fortune includes castles and other valuable real estate as well as Goya and Velazquez paintings and a first edition of Cervantes' "Don Quixote."

Following the ceremony, Cayetana de Alba and her new husband went to the front door of the palace to greet the large crowd gathered there.

The duchess stepped out of her shoes and began dancing to the strains of traditional Sevillian music.

Though she is said to possess more noble titles than anyone else in the world, Cayetana de Alba sought permission from Spain's King Juan Carlos to marry for a third time.
