Kate's Very Public Confirmation Baby No. 4!

A Glowing Duchess of Cambridge Can’t Keep the Smile Off Her Face – or Her Hand Off Her Belly…

The Duchess of Cambridge has hinted heavily that she and Prince William may be increasing their family!

The 37-year-old – who is already mum to George, five, Charlotte, four, and 14-month-old Louis – was seen repeatedly resting her hand on her stomach as she mingled with members of the royal family at the Ascot races last week. ‘Kate was protectively holding hertum and full of smiles,’ a fellow racegoer spills. ‘She was obviously very happy and sharing good news.’ According to a report in Woman’s Day magazine, Kate’s due in December. ‘Which will make the holidays even more exciting,’ says a palace insider.
