Cobin Bleu was born Corbin Bleu Reivers on February 21, 1989 in Brooklyn, New York City, to Martha (Callari) and David Reivers, an actor. His mother is of Italian descent and his father is Jamaican.
Corbin began appearing in television commercials at the age two, for products such as Life cereal, Bounty, Hasbro, and Nabisco. It was at that time he also discovered his love for dance when he began taking jazz and ballet classes, usually the only boy in the class. By the age of four he was a model with the Ford Modeling Agency in New York. He appeared in print ads for stores such as Macy's, Gap, Target, and Toys R Us, and fashion spreads in Child, Parent, and American Baby magazines, as well as having his image on toys and game packaging. At age six Corbin appeared in his first professional theater production off Broadway playing an abandon homeless mute in the play "Tiny Tim is Dead".
During the summer of 2005 Corbin was cast as Chad in the Disney Channel Original Movie High School Musical (2006) which was directed by Kenny Ortega. Being a big fan of musical theater, Corbin was thrilled to be a part of this musical movie project in which he gets to showcase his dance skills.
