Kate Middleton and Prince William with their newborn son, Prince George are moving into their new Kensington Palace apartment (official residence of the Duke and Duchess of Cambridge) which has two nurseries, and it sparked the speculation concerning Kate's second pregnancy.

As we have reported earlier that the royal couple were allegedly hoping to be pregnant with their second baby by Christmas, but now there are rumours that Kate is already pregnant.

The royals' official residence which is 57-room apartment features one day and one night nursery, in its cover story, titled Inside Kate's New Home, the latest issue of Us Weekly reports

"The day nursery will become a play room as he grows up," according to Hollywood Life, a palace insider was quoted as saying by the American celebrity and entertainment magazine.

Even though the royal couple has only one child, Prince George, the two nurseries only fortify William and Kate's desire for a second baby.

"They'd love to be pregnant again by the end of the year. They want a brother or sister for George," a family source said.

As it was reported earlier that Kate Middleton and Prince William were willing to expand their family.

"William and Kate are very keen to start trying for baby No. 2," an insider told Life & Style magazine.

"They know this time will fly by, and they figure they might as well have another baby next year so they can deal with it all at the same time," source continued.

"William and Kate will be splitting their time during the holidays with Kate's family and the Queen in Sandringham House in Norfolk, so it would be the perfect moment for an announcement," another source added.

To settle down before the christening of Prince George, which will take place on 23rd October at The Chapel Royal, St James's Palace Prince William and Kate Middleton, along with Prince George, have moved into their newly renovated Kensington Palace apartment.
