 After her marriage, she allied herself with Louis' sister-in-law, Henriette, Duchess of Orléans, who was known at court as "Madame", and with whom he had (allegedly) fallen deeply in love.Their relationship is highly unlikely to have been sexual, although the Queen Mother was deeply concerned about it.When Henriette and Louis sought to hide their relationship from others, Olympia is said to have introduced one of Henriette's ladies-in-waiting, "Mademoiselle de La Vallière", to the King so that he might claim that his attendance upon Henriette and her ladies was based on his affection for Louise and not Henriette.
