Nicholas Jerry "Nick" Jonas (born September 16, 1992) is an American singer-songwriter, musician and actor best known as one of the Jonas Brothers, a pop-rock band he formed with his brothers Joe and Kevin. The Jonas Brothers originally started as an attempted solo singing career for Nick, but the record producer liked the sound when his brothers sang backup for him. He previously starred in the Disney Channel original series JONAS L.A. as Nick Lucas, alongside his brothers. He also starred in the Disney Channel original movie Camp Rock and Camp Rock 2: The Final Jam. He formed the band Nick Jonas & The Administration, which released its first album in 2010.

Jonas's career started when he was discovered at the age of six in a barber shop, while his mother was getting her hair cut and was referred to a professional show business manager. At the age of 7, he began performing on Broadway. He had acted in several plays, including A Christmas Carol (in 2000 as Tiny Tim and Scrooge at eight), Annie Get Your Gun (in 2001 as Little Jake), Beauty and the Beast (in 2002 as Chip), and Les Misérables (in 2003 as Gavroche). After Les Misérables closed, he performed in The Sound of Music (as Kurt) at the Paper Mill Playhouse.
