"Never Say Never" is a song by Canadian singer Justin Bieber. The song is used as the theme song for The Karate Kid, and features rap interludes from the film's star, Jaden Smith.
Originally a risque demo with sexual lyrics performed by American singer Travis Garland, it was written and produced by The Messengers, and Omarr Rambert. However, Bieber was tapped to record the song for the film. He re-wrote the song with the original artists along with Jaden Smith and his vocal producer Kuk Harrell, to feature inspirational lyrics to foil the film's theme.
The song was released for digital download in the United States on June 8, 2010. The song was later included as an acoustic track on the remix album My Worlds Acoustic (2010) and both the acoustic and single versions were on the compilation album My Worlds: The Collection (2010). To promote Bieber's 3D concert film of the same name, the song was released as the lead single and the only single from Bieber's second remix album, Never Say Never: The Remixes.
"Never Say Never" peaked within the top twenty in Canada, Norway, and New Zealand, while reaching the top forty in Australia, as well as charting in other international markets. After it was re-released as the lead single and the only single from – The Remixes, promoting his film, the single peaked at number eight on the Billboard Hot 100, becoming Bieber's second top-ten single in the United States.
Its accompanying music video, directed by Honey, features Smith and Bieber in a recording studio playing around and dancing, and is intercut with scenes from the film. He has notably performed the song on Today and on his My World Tour. Smith joined Bieber during the tour's stop at Madison Square Garden to perform the song for scenes in Justin Bieber: Never Say Never.
