Nicholas Jerry "Nick" Jonas is an American singer-songwriter and actor. He was born in Dallas, Texas, the son of Denise, a former sign language teacher and singer, and Paul Kevin Jonas Sr., a songwriter, musician and former ordained minister at a Pentecostal Assemblies of God church. He is of Italian, Irish, German, and Cherokee Indian descent. The Jonases are known for their wholesome, "family-friendly" image, and the brothers are all committed Evangelical Christians. They were home-schooled by their mother. In addition, to signify their vow to abstain from premarital sex, on their left-hand ring finger they all wear purity rings. Joe has said that the rings symbolize "a promise to ourselves and to God that we'll stay pure till marriage," and Nick had stated that "it's purity rings pretty awesome, and the rings are just one of our ways of kind of like being different than everybody else out there." They reportedly also abstain from alcohol, tobacco, and drugs.

Nick's career started when he was discovered at the age of 6 in a barber shop while his mother was getting her hair cut and was referred to as 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.

On August 17, 2007, Nick, along with his brothers, guest starred in an episode of Hannah Montana. The episode debuted alongside High School Musical 2 and a sneak peek of the new Disney Channel show Phineas and Ferb. The episode broke basic cable records with a record 10.7 million viewers and became basic cable's most watched series telecast ever.

Nick and his brothers, Joe and Kevin, filmed a Disney Channel Original Movie called Camp Rock where they play a band called "Connect Three." Joe plays the lead male role and lead singer "Shane Gray"; Nick plays the role of "Nate," a guitarist; and Kevin plays the role of "Jason," also a guitarist. A soundtrack for the movie was released on June 17, 2008. The movie premiered on June 20 in the USA on Disney Channel, and Canada on Family.

The Disney Channel reality short series, Jonas Brothers Living the Dream, premiered on Disney Channel on May 16, 2008. The show, which ran until September 5, 2008, documents Nick, Kevin, and Joe's lives on the Look Me In The Eyes Tour.

He and his brothers currently star as the Lucases, a pop band trying to live a normal life, in the Disney Channel Original Series, entitled JONAS, which premiered May 2, 2009.

In 2002 while performing in Beauty and the Beast, Nick had written a song with his father called "Joy to the World (A Christmas Prayer)." With background vocals from the Beauty and the Beast cast, Nick performed the song on the 2002 annual Broadway "Equity Fights AIDS" album, Broadway's Greatest Gifts: Carols for a Cure, Vol. 4. In November 2003, INO Records received a demo copy of "Joy to the World (A Christmas Prayer)." The label released the song to Christian radio, where it quickly became popular on Record & Radio's Christian Adult Contemporary Chart. While Nick was working on his solo project, Joe followed in his footsteps to Broadway, appearing in Baz Lurhmann's production of La Boheme.

By September 2004, an executive at Columbia Records found out about Nick's song. Nick was soon jointly signed to INO Records and Columbia Records and released the single "Dear God". A second single, "Joy to the World (A Christmas Prayer)" (a new solo recording), was released on November 16. It was supposed to be followed by a December release of a self-titled solo album Nicholas Jonas, but the album had been pushed back; it did, however, get a limited release. Nick, along with Kevin and Joe, had written several other songs for the album.

In early 2005, Columbia Records' new president, Steve Greenberg, listened to Nick's record. While Greenberg did not like the album, he did like Nick's voice.

After meeting with Nick and hearing the song, "Please Be Mine", written and performed by the brothers, Daylight/Columbia Records had decided to sign the three as a group act. After being signed to Columbia, the brothers considered naming their group "Sons of Jonas" before settling on the name "Jonas Brothers"

It's About Time, the brothers first album was released on August 8, 2006. According to the band's manager, it was only a "limited release" of a little over 50,000 copies. Because Sony was not interested in further promoting the band, the Jonas Brothersthen considered switching labels. The band was ultimately dropped by Columbia Records in early 2007.

After shortly being without a label, the Jonas Brotherssigned with Hollywood Records in February 2007. Around the same time, brothers began appearing in commercials for Baby Bottle Pops, singing the jingle. Their self-titled second album, Jonas Brothers was released on August 7, 2007. It reached number five on the Billboard Hot 200 chart in its first week.

The Jonas Brothers third studio album, A Little Bit Longer, was released in the United States on August 12, 2008. It sold 2 million copies worldwide. The Jonas brothers were listed number 9 on the richest pop acts of 2008 with Coldplay and Ac/dcmaking over 62 million.

Nick was diagnosed with Type I diabetes at the age of 13 and wears an OmniPod insulin pump to help him manage his diabetes. He has developed the Change for the Children Foundation. Partnering with five different charities, their goal is to raise money and awareness for diabetes.
