Did Princess Antoinette try to have her first husband, Alexandre Noghes created a Prince?
She wanted to have herself installed as regent and over throw her brother.
‘In about 1950 Antoinette, as the elder child, began to investigate the possibility of her replacing Prince Rainier on the throne of Monaco, with a view to her son eventually succeeding. She was supported in this endeavour by Jean-Charles Rey, president of the Conseil Nationale of Monaco, whom she had taken as a lover.
At this time Rainier was enjoying a 10-year affair with the beautiful French actress Gisèle Pascal, whom he had met when studying at Montpelier University. They were living together in a villa at St-Jean-Cap-Ferrat. Antoinette, who was of a meddlesome disposition, circulated the rumour that Gisèle was infertile, hoping to secure the succession for her own son.
It began to be said that a doctor had examined the actress and confirmed the rumour — which was later dispelled when she had a child in her marriage to the actor Raymond Pellegrin. At any event, Gisèle and Rainier split up in 1953, and the succession was finally assured in 1956 when he married Grace Kelly and went on to have three children of his own.’
