"He was witty and gallant, and gifted with manners so elegant and fascinating that they never failed to remove the first unfavourable impression caused by his excessive plainness"
from the Memoirs of Madame du Barry
gossip guide to the 18th century

"...as beautiful as the goddess of Love..."
although ancient, had no fortune left! Her friends persuaded her that gaining some titles will make her life more enjoyable, and of course having such goals gives one a reason to keep moving forward. It can also be assumed that her friends, may have pushed her in this direction for their own benefits.
So she earned the position by hand of Louis XV, on the condition that she came to personally thank him. Success! All her friends knew she would soon be a favorite! = benefits, favors and money for them!
gossip loving courtiers! Rumors started that she was a mistress, and this did not sit well with the Duc de Choiseul, who could not accept anyone who was not a fan of his. When word reached Adelaide that the duc was out to ruin her, she immediately pulled strings to meet with him face to face. She then presented all her letters from the king saying he was wrong to have thought ill of her and only an innocent friendship was retained.
"the duc d'Orléans would not accept the marriage of his son with the daughter of a bastard race."However, when word got out that the prince de Lamballe was not going to make it the duc d'Orléans changed his tune. If the only heir, Lamballe, died then Louise-Marie would become heiress to her fathers massive fortune, an estimated 3,000,000 livres/year! To make the wedding happen (think wedding planner) the duc de Choiseul (our little seducer) was able to obtain the kings permission. Making the duc d'Orléans a happy father-in-law-to-be.
This is when things get fun for me, crazy for Louise-Marie. This was when her brother miraculously began to gain health! So of course the duc d'Orléans backed out of the situation (many were upset at this blatant abandonment of plans). The prince of Condé saw an opportunity arise and made haste to arrange a marriage of Louise-Marie with his son, Louis Joseph de Bourbon (later the prince de Condé).
"You've grown fat, M. de Choiseul. You are losing your hair and going bald."
