Kate Middleton is not the only member of the royal family who is rumored to be expecting another baby.

It has now been claimed that Princess Eugenie, Zara Tindall, and Autumn Phillips are also expecting. A source told New Idea that Queen Elizabeth was shocked when she was informed with the happy news.

“Then when Zara revealed she was also expecting number three and Autumn revealed she was also pregnant with her third child; everyone was in complete shock,” the source said.

The insider went on to say that all female members of the royal family are expected to give birth in March. This is quite rare for royals who didn’t plan on having another baby together.

And with the upcoming arrival of four new royal youngsters, the palace is rumored to be in a state of panic.

“However, the palace is in a state of panic right now over when to announce each pregnancy officially, as they don’t want to give the impression that anyone is considered to be the most important and ‘the Queen’s favorite,’” the source said.

Her Majesty doesn’t play favorites when it comes to her great-grandchildren, but the same cannot be said about her children and in-laws. Multiple sources have claimed that Prince Andrew is the monarch’s favorite son.

In fact, even amid Prince Andrew’s sexual misconduct scandal, the 93-year-old royal never left his third child’s side.

There have also been claims that Sophie, Countess of Wessex, is the Queen’s favorite daughter-in-law. Not only does Her Majesty enjoy Sophie’s company; she also feels a sense of calm when they are together.

Lady Louise Windsor has also made it to the Queen’s list of favorite royals. The teenage daughter of Prince Andrew and Sophie reportedly endeared herself to her grandmother last summer while they were in Balmoral.

Prince William and Kate Middleton also became drawn to Lady Louise after she looked after Prince George and Princess Charlotte during her stay at the Queen’s vacation home.
