Nick Cannon: Oscars boycotters are 'wasting their voices'

'America's Got Talent' host Nick Cannon insists black celebrities shouldn't ''waste their voice'' hitting out at the lack of diversity in the Academy Awards nominations. Cannon has shared a two-minute clip of him reading out a poem called Oscar, in which he slams the Oscars as being ''fake gold and plastic'' and says his fellow stars should be voicing their opinions about more important struggles, such as issues in Syria.
