Actress says she's got a potty mouth

Keira Knightley reckons she’s picked up some bad habits from her mum Sharman MacDonald.

The actress – who doesn’t drink, smoke or do drugs – says she can’t help muttering obscenities.

‘That is my vice, swearing,’ she admits. ‘I really enjoy it.

‘But you know what, my mum swears quite a lot while my dad does not swear.’

Meanwhile, Keira, 23, hopes to star in a remake of My Fair Lady with George Clooney, 47.

‘It’s an interesting prospect,’ she tells the Daily Mirror. ‘But there’s nothing concrete.’

Her next role is in The Beautiful And The Damned, which she starts shooting in spring.
