London, Aug 20 - British actress Keira Knightley seems to have her pictures airbrushed for a better cleavage in her new ad for Chanel perfume.

Thesun.co.uk reports that the 24-year old posed for a poster for Chanel's Coco Mademoiselle perfume.

This is not the first time that she has had her breast enlarged for pictures. The posters for her movie 'King Arthur' were touched up too. Her make up artists for the hit movie 'Pirates of the Caribbean' had even painted shadows on her skin to make her cleavage look deeper.
