Keira Knightley has revealed that the spelling of her name is the result of a misspelling on her birth certificate.

But no, unfortunately she did not reveal that the spelling of her name should be ‘Ciara’ but rather that her parents had settled on ‘Kiera’ before she was born.

The Imitation Game actress told the hilarious story of her mum’s epic mistake, saying: “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 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.”

 Ouch – poor Mammy Knightley!

Keira went on to say that her dad was less than impressed when he discovered the mix-up, as Keira describes: “Apparently when she came back, he said ‘what the f**k? You’ve spelt her name wrong!’ What were they going to do though? Once it’s on the piece of paper, it’s on the piece of paper. And that’s me. A spelling error.”

We’re sure Keira and her husband James Righton will take extra care when putting their baby’s name on the register in a few months!
