One of his main assignments was to select young women as mistresses for his master. The tactic for this was to invite the young woman to a supper in a dining room in the palace of Versailles, and the monarch could examine her through a hole in the wall next door. If the king would find the girl sweet to his palate, she would then be informed and examined by Lebel, and later she was led into the boudoir of the king. They were otherwise housed at the Parc-aux-Cerfs. Among the lovers he provided for the king was Marguerite-Catherine Haynault, Lucie-Madeleine d'Estaing, Louise-Jeanne de Tiercelin de La Colleterie and Anne Couppier de Romans.
