Surprise, surprise, as I didn’t even know about the pregnancy. Prince Aimone of Savoia-Aosta, Duke of Aosta and Apulia, and his wife Princess Olga née Princess of Greece, had a daughter at Paris, France, on 14 December 2012, 9am. Mother and daughter are doing fine. She is a sister for Umberto (* 2009) and Amedeo (2011). The couple married in 2008.
Edit, 17 December 2012: The little princess has been named Isabella.
