During her early teen years, Ashley found herself hanging out with older girls, which impacted her self-esteem when she found them to be more mature and, in her mind, prettier than she was. Ashley describes herself as a "hot mess" as a teenager. Ashley's mother put her into modeling classes to improve her confidence, and Ashley began to consider becoming a model as a career. After being told she was too short to be a model, Ashley considered becoming a lawyer and getting a degree in psychology. She actually convinced her parents to let her leave her private school to attend a public one which had a law and psychology program. However, after taking a commercial class, which led to acting class, Ashley knew what she wanted to do - acting. Luckily for Ashley, her parents were supportive and allowed her to move to LA at seventeen years of age. Due to her excellent grades and extra credits, she was able to graduate high school early to follow her acting dream.
For three years, Ashley struggled to find acting roles. She picked up small roles here and there in TV shows such as Punk'd (2003) and Crossing Jordan (2001), and some very small film roles in Shrink (2009) and King of California (2007). Ashley's big break came when she got to audition for the film, Twilight (2008), based on Stephenie Meyer's popular book series. She originally auditioned for "Bella", but, as she says herself, "I was no Bella". She was called back to audition for the role of "Alice Cullen". After a long auditioning process, Ashley was finally told she got the part. Ashley had previously worked in restaurants but, like the rest of her fellow "Twilight" cast-mates, Ashley found herself suddenly thrust into the limelight. Though she says she doesn't get the same kind of insanity as the boys - especially Robert Pattinson. She says most fans relate to her on a "best friend" level rather than screaming at her hysterically. Ashley has already begun filming other roles and has high hopes for her career outside of the "Twilight" franchise. She has said she wants to be a superhero, a Bond girl and possibly Wonder Woman in future projects.
