Rap group Bone Thugs-N-Harmony will split for good next year (15) after releasing a final album and completing a farewell tour, according to a U.S. report.

The band, which has been part of the music industry since 1991, will reportedly bow out in 2015 after 23 years.

Editors at Tmz.com report the five original members will head into the studio to record one last album, before going on a world tour which will mark the end of their time together.

The report also suggests they will follow in the footsteps of Wu-Tang Clan by auctioning off one copy of the record for at least $1 million (£588,235).

The tour is said to be slated to start in December (14).
