A magazine in the US reported the couple are expecting their first child, and that they would break the news officially once back from their honeymoon.
They quoted a source close to the couple as saying: 'Kate's bursting with the secret knowledge that she could soon be a mum,' adding 'She had originally been nervous about having morning sickness on the wedding day, but in the end she decided not to put it off, to just leave it up to fate.'
A Buckingham Palace spokesman flatly denied the rumours, branding them 'absurd' and 'certainly not true'.
And given that all the UK press is obsessed with how THIN Kate has been looking in the run up to her big day, a pregnancy does seem rather unlikely, doesn't it?
