Duchess of Alba and Alfonso Diez stepped out for a lunch in Paris

Spain’s Duchess of Alba and her younger husband Alfonso Diez were still very much enjoying married life six months after their wedding as they stepped out for a lunch date in Paris.

Duchess of Alba, 85, held hands with Alfonso Diez, 61,as they strolled the streets of the French capital.

Dressed head to toe in several different shades of blue – which included a hairpiece, shoes, dress and stockings – the eccentric billionairess clung to her husband’s arm as they browsed a book shop.

The couple married in a flamboyant ceremony last October; the bride, an eccentric billionaire with more titles than Queen Elizabeth II while her groom was a mere civil servant young enough to be her son.

But despite the objections of her six children – and plenty of public controversy – Spain’s Duchess of Alba wed Alfonso Diez at her 15th century palace in Seville.

The famously flamboyant Cayetana Fitz-James Stuart wore a delicate pale pink gown designed by Victorio y Lucchino for her third marriage, which took place in front of 38 guests.

Well-wishers donned fancy dress and wigs in an attempt to copy her quirky style as they celebrated in the city’s streets.

The twice-widowed Duchess’s children feared Alfonso Diez was a gold-digger – so he has relinquished his rights to her $5 billion fortune in an effort to appease them.

Duchess of Alba, who is a distant relative of Winston Churchill and Princess Diana, went ahead with the marriage despite her children’s qualms.

It emerged in August that she has divided her fortune between her six children to convince them that her suitor is besotted with her rather than her money.

Known now for her frizzy white hair, squeaky voice and wildly colorful clothes, the duchess is among Spain’s most famous people.

Last year, Duchess of Alba was at the centre of a sex scandal when Spanish magazine Interviu published a 30-year-old picture on its front cover of the duchess sunbathing topless in Ibiza.

Duchess of Alba and Alfonso Diez, a social security administration employee, are old acquaintances through her second husband, who was a former priest, and Diez’s brother.

They bumped into each other about three years ago outside a cinema in Madrid and eventually started dating.
