"I was meant to be named Kiera, after a Russian ice skater who was on the Tv one day. My dad fancied her and nicked (stole) her name for me. But it was my mum who went to register my birth, and she accidentally spelled ‘ei’ instead of ‘ie’ because my mum’s crap at spelling. Apparently, when she came back he (father) said, 'What The F**? You’ve spelt her name wrong...!' And that’s me. A spelling error." Actress Keira Knightley reveals her mum blundered on her birth certificate.
