However, it was all an illusion, which was made to look real by the film-studio art of "bosom make-up". This old-age skill of Hollywood went into oblivion with the a. "They painted my t**s on me for the films, which is extraordinary because it's kind of a dying art form - in the past, they used to have whole sections of the studios devoted to bosom make-up. And I loved it, completely loved it. Because it was the first time in my life I had big t**s, and I didn't even need surgery," The Daily Telegraph quoted Keira, as saying.
She revealed that it used to take the make-up artists almost 45-minutes every morning to create that eye-grabbing cleavage for the actress, before she started filming. The chest make-up required the artist to apply a slightly darker shade of base make-up between Knightley's own breasts to create a shadow to increase the 'cleavage effect'.
Keira had her assets digitally enhanced in movie posters for her 2004 film King Arthur. While in British versions she appeared in her natural state, in posters for the US they had grown to a C-cup size, leading to a hullaboo among cinema-goers.
