Proud, lazy and attractive, she successfully intrigued to have her daughters marry well to the Prince of Conti, Duke of Berry, Duke of Modena and King of Spain, mostly to spite her sister Louise Françoise de Bourbon, the Duchess of Bourbon.

She was involved in the Cellamare Conspiracy in 1718 which was supposed to overthrow her own husband Philippe d'Orléans as Regent of the Kingdom and replace him with her favourite brother the Duke of Maine. The "marquis d'Argenson" said she was very like her mother, Madame de Montespan, but also had Louis XIV's orderly mind with his failings of injustice and harshness.
