New York: After supermodel Naomi Campbell was compared to a chocolate bar, she is set to take legal action against Cadbury over the racist commercial.

The 40-year-old is considering "every option available" following the chocolate giant's refusal to pull the controversial campaign, reported a news channel.

The supermodel is accusing Cadbury of racism over their tag line to promote its new 'Bliss' chocolate bar which reads, "Move over Naomi, there is a new diva in town".

Campbell reacted angrily to the campaign, saying, "I am shocked. It's upsetting to be described as chocolate, not just for me, but for all black women and black people. I do not find any humour in this. It is insulting and hurtful".

The company, run by US giant Kraft, denied to pull the campaign despite Campbell's grievances.

She has found support in the group 'Operation Black Vote', with spokesman Simon Woolley saying, "Racism in the playground starts with black children being called 'chocolate bar'. At best, this is insensitive, and at worst it demonstrates Cadbury's utter disregard for causing offence".
