Aria lives with her parents and "Uncle Dedrick" in a luxury penthouse and later normal apartment. As a young adult, she ran a blog called "That Girl Who Talks Shit", where she gossips and bashes various celebrities (usually Dedrick, because he has such a scandalous love life), in a Perez Hilton-esque way, which prompted LifeSimmer to title Part 32 of the LP "Aria Hilton". Aria also uses her blog to victimize one of Dedrick's many lovers, Sun Young Kim, for living illegally in Bridgeport.
As a teen, Aria would very rarely, if ever, attend school. Aria skipped school on her birthday to go to the day spa, and left school with a fail, which caused her Hates the Outdoors trait. However, despite almost never attending school Aria was still very popular among her peers and was even voted Prom Queen, although she didn't have a date to her prom; she tried wooing a male babysitter, but he left before they could hit it off. Aria wore a glamorous, jewel-embedded turquoise gown to her prom. Later on in her teen years, she started wearing this gown around the house and the city with no explanation.
Young Adult Aria had a failed plastic surgery in Part 23 and had to undergo a corrective surgery afterward. Unfortunately, this meant that Aria lost the unique eye shape which she had inherited from Matthew. In Part 37, she tried for a baby with a vampire named Vladimir Schlick; Aria later gave birth to a son named Blade.
- A controversial viewer suggestion at the time of the LP was that Aria dates Dedrick Lofton. This was generally dismissed as creepy.
