After the Duke and Duchess of Cambridge spent their summer holiday in France with Prince George and Princess Charlotte, reports claim that Kate Middleton is pregnant with a new baby girl.

"It's official! She is due on Christmas. Kate and William are overjoyed," an insider tells Life & Style about the pregnancy of the Duchess.

According to the source, the Duke and Duchess want at least four children to follow in the monarch's footsteps.

"They don't mind whether No. 3 is a boy or a girl. They already have one of each, so they just want their next child to be healthy," the insider shared.

Reports also revealed that the couple's third child will be due in December.

Furthermore, followers of the royal couple have reportedly noticed Kate Middleton's growing baby bump in all of her recent photos. Some also believed that Duke and Duchess have decided to have another baby in order to save their failing marriage.

While it's a joy for everyone for the couple's expected third baby, this seems not a very good news to Queen Elizabeth as she is reportedly not happy with Kate Middleton's pregnancy.

Reports claimed that there is an ongoing feud between Kate Middleton and Queen Elizabeth as sources claimed that Prince William's grandmother is mad at his wife for using pregnancy to escape royal duties.

The Duke and Duchess of Cambridge have been criticized for being the laziest royal couple in history for their work-allergy attitude towards the Palace's charities and royal engagements.

Reports added that both Prince William and Kate Middleton uses pregnancy plans just to get out of their royal assignments.

Furthermore, reports also revealed that Kate Middleton's current pregnancy will give her more time to stay at home rather than going to events and engagements that Queen Elizabeth would like her to attend to.
