However, it was not her cousin Philip whom Alexandra finally married. In 1942, the Princess met her third cousin, King Peter II of Yugoslavia in an officers' gala at Grosvenor House. The 19-year-old sovereign had lived in exile in London since the invasion of his country by the Axis powers on 6 April 1941. Quickly, they fell in love with each other and considered marriage, which greatly delighted Princess Aspasia. However, the sharp opposition of Queen Maria of Yugoslavia, Peter II's mother, and the Yugoslav government-in-exile, which deemed it indecent to celebrate a wedding while Yugoslavia was dismembered and occupied, prevented for a while the marital project. For two years, the lovers had only brief meetings in the residence of the Duchess of Kent.
