Fingers crossed it's a girl! Both Brits and Americans are hoping Kate Middleton has a royal baby in pink (But while we want her to be called Charlotte, the US favour Diana) 

With superfans already eagerly camped out at St. Mary's Hospital ahead of Kate Middleton's due date, it seems that the birth of Prince George in 2013 did nothing to diminish the undeniable global fascination surrounding royal babies.

And it's not just Brits that are starting to make excited estimations, the frenzy has reached America where there are more than a few guesses about royal baby particulars.

International research firm, YouGov, has conducted a poll asking the UK and the US their opinions on the second child, and it turns out, views are not too different.

William and Kate are currently prepping for the birth of the second royal baby, which has spurred guesses on the sex and name

Questioning 1713 Brits and 1124 Americans, the survey revealed that after the excitement of a baby boy in blue in 2013, this time around, both desire a baby girl.

In fact, this landslide opinion was only contested by two per cent of Brits and seven per cent of Americans, who alternatively want Prince George to have a baby brother.

When it comes down to a name for William and Kate's potential little girl, the survey revealed discrepancies between what Brits and Americans want.

In the UK, Charlotte, Alice and Alexandra are the leading names, with Charlotte scooping the lead with 13 per cent.

Americans instead favour distinctively prominent royal names, with the top three being Diana at 19 per cent, and Elizabeth and Victoria tying at 12 per cent in terms of popularity.

Princess Diana was the much-celebrated first wife of Prince Charles, and also the mother of Prince William, before passing away in 1997. 

The popularity of the name Elizabeth is most likely derived from the name of the current queen, Elizabeth II. 

Similarly, the popularity of the name Victoria, is from Queen Victoria, whose reign of nearly 64 years is the longest of any other British monarch.

When it comes down the names for a potential baby boy, the survey revealed much more unified results.

Both Brits and Americans agree on James, Richard and Arthur as their favourite top three boy names, with James scooping the lead, at 27 per cent in the UK and 15 per cent in the US, in terms of popularity.

Americans have picked Diana and Elizabeth as their favourite names if the royal baby is in fact a girl. The popularity of these names could have stemmed from prominent names of other royals, including the late Princess Diana (pictured left) and Queen Elizabeth II (pictured right)

And it's not only immediate particulars about the unborn baby's life being discussed; people were also keen to throw in their two cents about the most suitable roles for the child's later life.

Both were in agreement that in the future, baby number two should focus on acting as a good role model for young people.

Opinions divided when it came to the second most important role.While Brits believe the second child of William and Kate should also prioritise having a job, Americans feel that the next priority should be raising money for charity. 

Although American are showing some interest in the new royal baby, the majority of the US are far less interested in the latest arrival, in comparison to Prince George's birth in 2013.

According to a new survey by the University Of Southern California, American are five times less interested in the new royal baby than they were with George. 

Jeetendr Sehdev, professor of marketing at USC, told the Sunday Times:  'They were three times more interested in the birth of Jessica Biel and Justin Timberlake's baby and equally excited by the [forthcoming] birth of Sophie Hunter and Benedict Cumberbatch's child.

'Only one in 10 Americans describe themselves as excited about the second royal baby. Some of this is inevitable but it also represents a wider attitudinal shift across the US. 

'Americans still love Great Britain ... but the royals are now part of that, not the face of it.'
