Jessie Ward was born in New Jersey on February 18, 1982. She is a classically trained ballerina and began studying ballet seriously at the age of nine. She lived and studied at the School of American Ballet as a teenager and attended high school at the Professional Children's School in New York. She was chosen as the highest-scoring dancer in the US by Britain's Royal Academy of Dancing, earning her a ballet scholarship to study in England. She has performed numerous solo and principal roles with various professional ballet companies, and her inspiration for the arts began with dancing and evolved into a love for acting.

Pursuing her acting career, she left New York for Los Angeles, and has appeared in numerous national television commercials as well as performing in a music video with Jennifer Lopez. In March of 2006 she landed a guest role as Brianna on F/X Network's It's Always Sunny in Philadelphia (2005) alongside Eddie Mekka and Danny DeVito. Wicked Wicked Games (2006) marks Ward's second appearance on MyNetworkTV, having previously played the role of Penelope on Desire (2006).
