A song recorded by Michael Jackson and featuring vocals by Justin Bieber has surfaced online.
Slave 2 The Rhythm was written by Jackson just before his death in 2009.
Bieber later added his vocals to the song to create the duet.
The song has since been verified by Bieber via Twitter.
"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," Bieber wrote.
Capitol Radio London has already played the song.
A Jackson only version of the song previously surfaced not long after Jackson died.
