Isabella Fiorello is one of the pre-created, yet unplayable Sims featured in The Sims 2 as ancestors of playable, pre-created Sims. Though deceased when the game begins, you can see her in the relationship tree of playable Sim Don Lothario, who is her grandson.
She resided, during her lifetime, in Pleasantview, one of the neighborhoods that ships with the game. She is the mother of Adriana Lothario and grandmother of the neighborhood womanizer, Romance-Sim, Don Lothario. Her husband was Primo Fiorello. She and her husband are possibly parodies of Patrizio and Isabella Monty since they have common names, look alike, and wear the same things (except for Isabella Monty).
