British actress Keira Knightley who arrived without pop star boyfriend Kaz James, looked sexy and stunning in a low-cut purple dress combined with luscious new hair extensions, at the London premiere of her movie ‘Pride and Prejudice’.

Keira confessed she hates photographs of her being airbrushed to make her look sexier, even though she suffers from severe acne. The actress was rumoured to have been digitally improved in the promotional posters for ‘Pride and Prejudice’.

She said “I’m not too comfortable with the way I’m portrayed. It’s impossible to attain that level of perfection. So if that’s the image you’re presenting and saying, ‘This is what you should look like,’ then I don’t think that’s right because no body can look like that.”

She claimed the much-used technique gives a false impression of how women should look to young girls.

However, Keira admits she would love it if her spots could be ‘airbrushed’ before she went out shopping. “Although I do suffer from terrible acne, I wish they could change me in my day-to-day life.”
