Hip-hop stars urged to boycott their favoured bubbly

Rap mogul Jay-Z has called on hip hop stars to boycott their favourite posh champagne, saying the company’s boss suggested their dedication to the brand was unwelcome.

Artists like P Diddy, 50 Cent and Snoop Dogg helped transform Cristal bubbly - first favoured by the Russian tsars – into the tipple of choice for the scene’s movers and shakers, with performers frequently name-checking the booze in their lyrics.
