the instigators behind the rumor that the king had asked Adolph Fredrik Munk af Fulkila to impregnate the queen and that Munck was consequently the father of the father the Crown Prince: the queen dowager supported this hypothesis, and Löwen took the side of the queen dowager against the king during the scandal, which caused her to fall out of favor with Gustav III. A partial reconciliation followed two years later. Socialite Eva Löwen was a leading figure of Stockholm aristocratic and royal society life, described as a celebrated beauty, the capital's “Queen of fashion” and talked about for her love adventures. It is mentioned, how various clothing attires such as a specific model of a cap became fashionable after having been worn by her. Johan Fischerström said of her that she "has good sense and sweet judgments; pleasing ways and are created for the life at court". In 1767, she became the subject of a scandal when her spouse, after having been told by a footman, returned home to find her with her lover, the French envoy Louis Auguste Le Tonnelier de Breteuil, who was forced to bribe the servants to be able to flee the scene. In 1772, she had a relationship with count Axel von Fersen the Elder, who was in 1774 replaced by his son, count Axel von Fersen the Younger, and then with the French envoy count Claude Bigot de Sainte-Croix, whom she shared with Sophie Piper. Count Claes Julius Ekeblad described the affair between Eva Löwen and Axel von Fersen the Elder to Brita Horn in 1774: "He loves her passionately. But his thoughtlessness and childishness makes her insecure enough for her entire coquetry to become unhinged. He is a true Lindor, whom you must forgive everything, and I do believe, that she does." In 1788, her son Adolph Ribbing fall out of favor with the monarch because of a scandalous duel with Hans Henric von Essen, and came to belong to the opposition of the king. In 1792, he belonged to the participators of the regicide of Gustav III, and lived for the rest of his life in exile. The whole affair of her son's involvement in the regicide reportedly affected her deeply, and she continued to support him financially. By that time widowed for thirteen years, she married Baron Gustaf Macklean (1744-1804), who had been her lover for twelve years, in 1796.
