She served as premiere femme du chambre to the queen of France, Maria Theresa of Spain.
Marie Therese brought a large Spanish entourage with her upon her arrival, which formed her household together with the new French courtiers appointed to her.
However, when Louis XIV found the queen to favor her Spanish courtiers too much, the majority of them were sent home.
She was given the French title of premiere femme du chambre and as such had great informal influence in the household of the queen.
She is noted to have been a personal favorite and confidante of Marie Therese, and reportedly often slept in her bedchamber, comforting her when she was inflicted by anxiety and nightmares, which forced the king to order her out when he visited the queen in her bedchamber.
