Cassidy grew up in Calabasas, California where she now currently lives with her mother, stepfather Richard, and half-sisters Jenna and Jamie.
As a child, Cassidy took gymnastics and eventually became a cheerleader for the California Flyers, a competitive team. She eventually cheered as a freshman for Calabasas High School where she attended classes.
As a teenager, Cassidy became interested in show business. She took acting, singing and dance lessons. Despite her father's disapproval, she landed a deal with Artemis Records to cover his 70's hit, "I Think I Love You". Cassidy was able to land a role in "Bubblegum Babylon", VH1's TV special on pop idols and the music business to help promote her singing career. Unfortunately, her cover failed to attract a large number of fans or a record deal.
While she was still signed with Artemis Records, she was introduced to the popular boyband Dream Street. This is where she first met Greg Raposo. They dated for a few months in 2002. She also met her current boyfriend, Jesse McCartney, another member of the group.
After her stint in the music business, Cassidy turned to modelling. She modeled for Abercrombie and Fitch and Guess?'s Rock and Republic line in 2004. She reportedly has plans to continue her modeling in the future.
Modeling helped open the door to Cassidy's acting career. She landed a number of jobs, including a recurring role as Zoe on 7th Heaven, where she has appeared several times. Following that, she appeared in the one-hour drama, "Sex Love and Secrets". Unfortunately, the series was cancelled after a few episodes.
