On any state occasion, Madame Lannes outshone Lady Fitzgerald (wife of the British ambassador) because she was elegant, clever, lovely, and exercised tact and discretion at all times.

Attending the opening night of the opera in Lisbon as the honored guests of the prince regent, the French ambassador and his wife completely eclipsed their British counterparts.

The Portuguese nobility dearly loved a show of beauty, grace, and conspicuous consumption, and Lannes was not above putting his best foot forward—not his own in this case but his wife's.

The Duchess of Montebello enjoyed a great deal of respect in the contemporary Parisian high society as a role model of aristocratic femininity.

After her arrival to France, Marie Louise was allowed to keep only one person of her Austrian entourage, her former governess countess Lazansky, who was her trusted confidante.

Montebello, however, complained to Napoleon that she would not be able to act as a guide of the empress as long as she was allowed to keep her Austrian favorite, and Lazansky was therefore sent back to Vienna with Marie Louise's dog the same year.

[5] This was reportedly a traumatic event for Marie Louise, who had attached herself to Lazansky ever since her first governess, countess Colloredo, who had been as a mother for her, had left her position during her childhood.

[5] When Marie Louise was encouraged to return to Paris before the Bourbons did to secure the throne for her son after the abdication of Napoleon, she was reportedly willing to do so after a conversation with her dame d'annonce Mme Durand, but changed her mind and decided to stay on the advice of Montebello and Corvisart.
