A new duet featuring Justin Bieber and Michael Jackson has surfaced online.

The song, Slave 2 the Rhythm was recorded by Jackson just before his death in 2009 but the new version with vocals of Bieber’s that were later added in has become available to hear online.

Justin has confirmed that the song is genuine to his followers on Twitter having tweeted: “Excited for what is to come. MJ set the bar. Not only for music but for an entertainer and how you treat fans. Wish he was here.”

The song was written by Michael before his death but the newer version contains lyrics added in by Bieber with some of the vocals from Jackson being replaced by Bieber’s.

Capitol Radio London has already played the song so it could be set for an official release in the not too distant future.

A Michael Jackson version of the song is also available.
