...In April Princess Caroline became engaged to her long-term lover Robertino Rossellini and began planning a September wedding. The pair, who had been together since Caroline divorced Philippe Junot in October 1980, had been brought closer together by tragedy. Rossellini's mother Ingrid Bergman had died of cancer in August 1982, just fifteen days before Princess Grace's accident. Later that year Caroline travelled to the tiny Swedish fishing village of Fjallbacka and solemnly watched Rossellini scatter the ashes of his mother.

Instead, Caroline joined some Italian friends on their yacht to cruise the Mediterranean to Sardinia. And met a man who would change her life.
Stefano Casiraghi, the handsome twenty-three-year-old heir to a Milanese oil-refining and construction fortune, had first met Caroline a year earlier at Jimmy'z nightclub in Monaco. Although Caroline was with Rossellini at the time, their companions noticed she and Stefano had a great rapport.
'I felt right away there was something in the air,' said Casiraghi's then-girlfriend Pinuccia Macheda....
Thank you very much Thecia!
