Hip-hop stars Kanye West, Jadakiss, Paul Wall and Tego Calderon will head to Sierra Leone, Africa, for the documentary Bling: A Planet Rock.

The film chronicles the diamond wars of Sierra Leone and how hip-hop's 'bling' culture of wearing flashy jewellery has unknowingly fuelled such conflicts.

The movie is being made by independent production company Article 19, which is named after the United Nations (un) human rights declaration and makes socially conscious films.

Bling is being co-produced with US network Vh1 and part of the film's budget is being funded by the United Nations.

A portion of the proceeds from the film will go to charity.
