Snow was born in Tampa, Florida to Cinda, who works for Prentice Hall, and John Snow, who worked in insurance and now organizes Snow's schedule. She is also a close personal friend of High School Musical's Ashley Tisdale.
Snow began modeling at the age of three in a print ad for Burdines. She had a popular role at age twelve as troubled teen Susan LeMay on the soap opera Guiding Light from 1998 to 2001. She is perhaps best known for playing Meg Pryor on NBC's American Dreams and Ariel, a neo-Nazi high school student on the third season of Nip/Tuck. In 2005, Snow appeared in The Pacifier with action star Vin Diesel. In 2006, Snow was in the film John Tucker Must Die and voiced Naminé in the video game Kingdom Hearts II as well as Shizuku in the Hayao Miyazaki film, "Whisper of the Heart". Snow most recently appeared in Hairspray, a film adaptation of the Broadway musical, playing the bratty Corny Collins show queen Amber von Tussle alongside James Marsden. With her role in Hairspray, Snow shows a singing side of her in numerous numbers including a solo entitled, "The New Girl In Town", a song previously cut from the Broadway musical version. She will soon be seen in the horror film "Prom Night", a remake of the hit horror film of the same name, starring Jamie Lee Curtis. Snow will be playing the lead role, who is traumatized (along with her friends) by a deranged killer on her school's prom night.
