After moving to Paris, from her position at the Folies she became a noted
demimondaine, rival of "
La Belle Otero". She took her last name from one of her paramours, a Comte or Vicomte de Pougy. Actress
Sarah Bernhardt, faced with the task of teaching Liane to act, advised her that when she was on stage, it would be best to keep her "pretty mouth shut". Her
lesbian affair with writer
Natalie Clifford Barney is recorded in her novel
Idylle Saphique, published around
1901. In
1899, after seeing de Pougy at a dance hall in Paris, Barney presented herself at de Pougy's residence in a page costume and announced that she was a "page of love" sent by
Sappho. Although de Pougy was one of the most famous women in France at the time, constantly sought after by wealthy and titled men, Barney's audacity charmed and seduced her. The two were said to have had deep feelings for one another for the remainder of their lives.
