Bookies have reported a surge in the number of bets placed on the Duchess of Cambridge welcoming a daughter in April 2015 - and on William and Kate picking the name Charlotte for the spare to the heir.
The odds that Prince George will soon have a baby sister now stand at 10/11 and according to William Hill this surge could mean that Kate dropped a hint about her baby's gender during the royal couple's recent trip to New York.
William Hill spokesman Rupert Adams told OK! magazine: "These two gambles have come out of the blue, and you have to wonder if a hint has been dropped on the royal visit.
"One thing is for certain, we don't think William and Kate will choose the name LeBron or Barack both of which are 100/1 outsiders."
Could the name choice be inspired by an encounter on their recent trip?
While in New York, William and Kate met Hilary and Chelsea Clinton at the British Consulate. Talk inevitably turned to babies as Chelsea gave birth to her first child five months ago - a daughter named... you guessed it, Charlotte.
And should the baby turn out to be a boy, people are placing their money on him being called James, Arthur or Henry.
