Keira KnightleyKeira Knightley has reportedly refused to let movie bosses increase the size of her bust in the publicity pictures for her new film The Duchess.

Keira’s chest was famously enhanced in posters for her 2004 film King Arthur and the actress said she “didn’t give a sh*t” about it - but apparently now she does.

A source close to the actress claims: “She looks flat-chested in the whole movie [and] she has insisted that her figure stay in its natural state [for the promotional pictures too].

“She is proud of her body and doesn’t want it altered.”

The period drama, about a scandalous 18th century aristocrat, is set to be released in the UK in September.
