YOUNG JUSTICE: VOICE ACTORS

Following are biographies of the actors providing voices for the main cast in Cartoon Network's Young Justice.

JESSE MCCARTNEY (ROBIN)

Actor and recording artist Jesse McCartney was just 14 when he recorded his first gold record, with the short-lived group Dream Team. In 2008, McCartney released his third solo album, Departure, that showcased an edgier pop/R&B sound. The album's first hit single, "Leavin'," was a blockbuster smash, becoming the #1 most played Top 40 single of the year. The song spent 6 weeks at #1 on the Top 40 Chart and went on to sell more than 2 million digital downloads on iTunes.

McCartney has written songs for other artists, and one of those -- "Bleeding Love," a collaboration with One Republic's Ryan Tedder -- turned into the top song of 2008 for Leona Lewis, becoming one of the biggest songs of the decade. McCartney also contributed a track to the Step Up 3D soundtrack, where he"s featured alongside Trey Songz and Flo Rida.

McCartney began his acting career with a three-year stint on the popular daytime drama All My Children. He went on to land a series regular role on Summerland, a multi-episode arc on Greek, and appearances on Law & Order and Law & Order: Special Victims Unit. McCartney has also lent his voice to animated features, including Theodore in the Alvin and the Chipmunks franchise. In early 2011, he'll be back at work, talking very slowly as he again gives voice to Theodore for the third (and 3D) edition of the film.
