After spending winter in Italy, the Fitzgeralds returned to France, where they would alternate between Paris and the French Riviera until 1926. Fitzgerald began writing his fourth novel, provisionally titled "The Boy Who Killed His Mother", "Our Type", and then "The World’s Fair". During this period, he became friends with many members of the American expatriate community in Paris, later known as the Lost Generation. Most notable among them was a relatively unknown Ernest Hemingway, whom Fitzgerald greatly admired. Fitzgerald's friendship with Hemingway was quite effusive, as many of Fitzgerald's relationships would prove to be. Hemingway did not get on well with Zelda, however, and in addition to describing her as "insane" in his memoir "A Moveable Feast", Hemingway claimed that Zelda "encouraged her husband to drink so as to distract Fitzgerald from his work on his novel", so he could work on the short stories he sold to magazines to help support their lifestyle. Like most professional authors at the time, Fitzgerald supplemented his income by writing short stories for such magazines as "The Saturday Evening Post", "Collier's Weekly", and "Esquire", and sold his stories and novels to Hollywood studios. This "whoring", as Fitzgerald and Hemingway called these sales, was a sore point in the two authors' friendship. Fitzgerald claimed that he would first write his stories in an 'authentic' manner, then rewrite them to put in the "twists that made them into salable magazine stories". Upon reading "The Great Gatsby", Hemingway was so impressed with the book that he vowed to put any differences with Fitzgerald aside and "be of any help could" with a subsequent novel, fearing Fitzgerald's personal problems may hamper his writing career.
