New York, July 20 - Ever since she has won the golden Oscar statuette for her performance in 'The Reader', British actress Kate Winslet feels she can't be herself and is forced to 'look composed' all the time.

Imdb.com reports that the 33-year-old also admits she is now forced to live up to an impossible standard, and can't be true to her free spirit.

'It's very hard to feel like yourself because you're not; you're on show. In the old days I'd just wing it, but now you need to give people what they want, which is someone looking composed, fresh and put together. Our knickers will still go up our a** at the most inappropriate moment. And we'll still want to flick them out, but you can't, because someone is going to catch you.' Winslet told America's Harper's Bazaar magazine.
