Keira Knightley used to 'playact' version of trying to be 'grown-up'

Keira Knightley has revealed that she did playact a version of trying to be a grown-up, where she tried to be sensible, good and professional in a way she doesn't now.

The 29-year-old actress said that she was just very embarrassed at being young, probably because she had worked with people who were a lot older than her from such a young age, the Guardian reported.

The 'Begin Again' star, whose mother once claimed that her daughter was born 45, continued that not that she used to behave badly or did anything, but suddenly realised that she has set herself a very specific framework to live within, which can be quite claustrophobic and unnecessary.
