But a heated row has broken out between Cadbury and ageing supermodel turned author Naomi Campbell, who has accused the company of racism in a poster for its new Dairy Milk Bliss bar. 'Move over Naomi,' the ad advises. 'There's a new diva in town.' Ouch!
The "shocked" icon has interpreted the ad as a racial slur and is calling for an international boycott of products made by little-loved parent Kraft Foods.
"It's upsetting to be described as chocolate, not just for me but for all black people," she said.
Whether you feel the ad was insensitive, downright racist or just not very funny, it's easy to imagine the creatives behind it rolling their eyes wearily and cursing themselves for ever invoking the name of the famously litigious clotheshorse. As for whether there's really a new diva in town... as the saying goes, if you come at the king, you best not miss.
