Spice Girl Mel B and Reverend Run, (that being one half of hip-hop group Run DMC for those of you scratching yer heads), host tonight's Mobo Awards from London's Wembley Arena. The event, which returns to the BBC for the fifth year running, is one of the music industry's most glittering annual awards. In a year that has seen British black music rise to the top of the charts, Leona Lewis, Estelle, Dizzee Rascal and Wiley are the most nominated artists at the 13th annual Mobo Awards. Other contenders include Adele, Duffy, Chris Brown and Jay-Z. Among tonight's exclusive performances are John Legend, Jay Sean, Estelle, Flo Rida and Sugababes, who collaborate with Taio Cruz.
