Prince William baby report not true: Representative

Prince Williams' representative has denied reports of a US tabloid, which claimed that the royal's girlfriend Kate Middleton is secretly pregnant.

The editors of Star magazine have run a front-page expose on the young couple, featuring the headline, "William's princess bride pregnant!"

"William was up at his military base in North Wales when Kate called him. She was sobbing so hard, she could hardly get the words out. She told him that despite their precautions, she is pregnant," the Daily Express quoted a source as telling the publication.

"Behind the scenes, the royal circles are in absolute panic. They just don't know what they're going to do," the insider added.

A spokesperson for the Prince's official London residence, Clarence House, has denied the report, insisting it's "not at all true".

"This is a load of rubbish," added the representative.
