Keira KnightleyKeira Knightley reckons she's found a way to stop chatter about her weight.

After hearing her answer, she should be declared a genius.

Because she reckons getting up the duff is the answer.

According to the Daily Mirror, to halt nasty chatter about her being too thin, she's said: "That's a good reason to have a kid.

"Oh Good. They won't say I'm anorexic any more. S**t, I've got to have a child.

"I can't win. One week I'm anorexic and now my curves are too big.

"I mean really? It's a joke. What's next? Am I too tall, too short? Well, I'm sorry, I'm me.

"It's so predictable to be asked about it, but to me it's not appropriate."

Don't get too excited about the idea of a mini-Keira just yet, however.

She also told Canada's National Post that her boyf, Rupert Friend, is in no hurry to tie the knot or pop out sprogs.

So Keira, we guess we'll put a hold on ordering you those maternity dresses, then?
