Lauren is very jealous of bella When Bella moves to Forks, the instant attention she receives makes Lauren envious, and she remains hostile towards her for the rest of Twilight and New Moon. Bella figured out that Lauren was particularly jealous of the attention she was receiving from Tyler Crowley, whom Lauren obviously had a crush on. Lauren went to prom with Conner in Twilight.
Sometime during the summer following her junior year, Lauren was approached by an alleged modeling agent in a mall in Victoria, British Columbia, Canada, who told her that she seemed like a natural model. The agent told her that if she cut her hair shorter and edgier and had some high-quality headshots taken, her future would be assured. Lauren followed his instructions - spending 300 dollars on a haircut and 15 grand on pictures taken by the agent's partner - and never heard from the agent again.
Though they share the same lunch table, Lauren is still very hostile towards Bella in Eclipse. Jessica goes to hug her goodbye on graduation day. She also appeared at the Cullens' graduation party, which Bella commented her critical eyes for being "alight with curiosity".
Lauren is described as having long, cornsilk, blonde hair, green, fishy eyes with pale eyebrows, and 5'6" tall. In New Moon, Bella notices that during the summer break, Lauren had her hair cropped short like a boy. The reason Lauren cut her hair was due to being told that she had the potential to be a model if she used that particular style; the agency never called. When Bella sees her hair in this style she wonders if she got gum stuck in it, if she sold it, or if all the people she had been nasty to had come after her and shaved her hair off. Lauren also has a nasal-sounding voice.
She is depicted as being jealous of everyone pretty, despite being the most popular girl at school. Lauren is also standoffish and snobby. In Eclipse, Bella refers to her as the heart of the dark side of their lunch table.
