Jay-Z collaborates with Justin Timberlake, Beyonce and Pharrell Williams on one track.

The rapper's song 'BBC' for his forthcoming album 'Magna Carta Holy Grail' has a total of six guests, including the singers, producers Swizz Beatz and Timbaland and rapper Nas.

The lyrics include name-checking a number of brands, including the line: ''Bally shoes / Gucci sneakers / Pharrell's a Pharaoh / peep the features / unlaced Adidas / top of the world like pyramids / in Giza / Fila sweats.''

Jay-Z was photographed in the studio weeks ago with Timberlake, Nas, and Timbaland, working on the song.

He has also recently invested in an artwork by Swizz, buying the picture 'Holy Grail' - a portrait of graffiti artist Jean-Michel Basquiat - to raise money for the Children's Cancer & Blood Foundation.

'Magna Carta Holy Grail' will be released on July 4, and will also feature lyrics from REM's 'Losing My Religion' and 'Smells Like Teen Spirit' by Nirvana.

Last week it was rumoured Jay-Z and Beyonce are planning to release an album of duets together in 2014.
