Supermodel Naomi Campbell is considering suing the Kraft Foods-owned chocolate maker Cadbury, over an advertising campaign she claimed was racist.
The ad, which appeared on billboards and in magazines, featured a Bliss bar on a mound of diamonds with the slogan: "Move over Naomi, there's a new diva in town."
The ad appears to refer to Campbell receiving so-called "blood diamonds" from the then-Liberian leader Charles Taylor in a 1997 incident.
Campbell says she's "considering every option available" after her name was used to promote Cadbury Dairy Milk Bliss bars.
