New trouble is brewing among the troubled royals of Monaco. The buzz at last weekend’s wedding of Crown Princess Victoria of Sweden and Daniel Westling was that Princess Caroline of Monaco doesn’t like Charlene Wittstock, the South African fiancée of her brother, Prince Albert. “Caroline has been the de facto first lady of Monaco since her mother, Princess Grace, died, but when Prince Albert marries, Charlene will become the first lady,” said one source. Meanwhile, Caroline’s son, Pierre Casiraghi, was in Formentera, Spain, with gorgeous Fiat heiress Beatrice Borromeo.
