There were rumors about her connection with the Saxon diplomat Count Friedrich von der Schulenberg, a Prince of Württemberg, Lord Charles Stewart and others. Goethe met her in Karlsbad, and admired her beauty; she had just started a new romance with Prince Louis Ferdinand of Prussia, who ended his relationship with Princess Eleonore of Solms-Hohensolms-Lich for her. The Prince soon died in the Battle of Saalfeld, and the princess returned once more to Vienna. She then became the mistress of the very influential Prince Klemens von Metternich and had a daughter by him in Vienna on 29 September 1810, whom she named Marie-Clementine after the natural father. While Prince Bagration was forced by the Tsar to officially acknowledge her paternity, Metternich, on his part, made no secrecy of his fatherhood and the girl even lived with the Prince's family from 1814 until getting married.
