On December 5th 1906, Lina Cavalieri gave tenor Enrico Caruso a passionate kiss in front of an astounded audience, caught completely by surprise by the opera singer’s intense gesture.

After that, “the most beautiful woman in the world”, as fans called her, also became “the kissing primadonna”: that “coup de théâtre” on the stage of New York’s Metropolitan Opera House made Umberto Giordano’s “Fedora” simply unforgettable, and brought Cavalieri great luck in her career.
