She served as Première dame d'honneur to the queen of France, Maria Theresa of Spain, from 1660 until 1664.

She was foremost known for her role in opposing the king's adultery with the queen's maids-of-honour, which resulted in her banishment from court.

The king reprimanded her and ordered her to stop interfering, asking her to consider the effects of his displeasure, and the advantages of her compliance.

After having consulted a priest, however, she remained steadfast in her opposition and attempts to prevent the king from gaining access to the bedchamber of the maids-of-honour, going so far as to have bars placed to the secret entries to the chamber.

The incident is described by Saint-Simon: She retired with her spouse to their countryside estates, but their banishment was revoked by the king on the wishes of his mother in 1666.
