She served as regent of Blois during Theobald's absence from in 1190–1191, and during the minority of their son Louis from 1191 until 1197.
The birth of yet another daughter instead of a desperately needed son was the final nail in the coffin of Eleanor and Louis's marriage, which was annulled on 21 March 1152, when Alix was not 2 years old.
She and Marie retained their legitimacy, and custody of the girls was awarded to the king.
Eleanor married Henry, Duke of Normandy, just eight weeks later on 18 May.
Her sister Marie married Theobald's brother Henry I, Count of Champagne.
