National treasure Cheryl Cole may not be likely to do another campaign with husband Ashley any time soon, but the Geordie lass is considered as one of the best options for companies to chose to promote their products. That's even despite the backlash for the highly complained about L'Oral Elive ad (pictured above) which used hair extensions.

The X Factor judge also has the highest positive 'buzz score' (80% positive) despite the negative media coverage that has surrounded her in the past and is seen as very 'playful', 'sympathetic' and 'outgoing', but is the least 'reserved', 'calm' and 'laid back' matching well to Coca Cola and New Look.

Spokesman for the researcher said: "Cheryl's mix of exciting, endearing and engaging traits seems to be a winning combination."
