Why so blue Duchess?
The quirky 86-year-old went for a bold blue head to toe look including a blue hairpiece, blue eyeliner and blue pantyhose as she stepped out in the French city for lunch and a browse around a book store.
Holding hands with her 61-year-old boy toy the Spanish aristocrat - with a fortune between $800 million and $4.7 billion - managed to steal the show with her interesting attire.
Despite her age, the Duchess - whose full name is Maria del Rosario Cayetana Alfnosa Victoria Eugenia Francisca Fitz-James Stuart y de Silva - has managed to make some racy headlines of her own.
She faced a sex scandal earlier this year when a 30 year-old photograph of her sunbathing topless made its way onto the cover of Spanish magazine Interviu.
