There were rumours abound that Prince William and Kate Middleton were going to have another baby. And the rumours seem to be confirmed by an unlikely source: their four-year-old daughter Charlotte.

Apparently, Charlotte, who recently started school, was heard speaking to a friend at school that her “mummy is having another girl.”

A source revealed that one of the teachers also overheard Charlotte, saying that Charlotte was speaking very loudly and was convinced that her mother was pregnant.

Another baby would be the fourth Royal to be born in the family and we wonder if SHE (since Charlotte also revealed the gender) will be as mischievous as her older sister.
