Speculation is rife that the Duke and Duchess of Cambridge are expecting a baby boy, after Prince William dropped a major hint about their third baby's gender.

Having witnessed Aston Villa player Jack Grealish score a match-winning goal against Cardiff City on Tuesday night, according to The Mirror the Prince told fans: "I'm going to insist the baby is called Jack ... or Jackie," he added after a pause.

But while William may have simply been caught up in the moment after his football team's win, the quip has resulted in bookies at ladbrokes slashing the odds of a baby Jack from 50/1 to just 25/1.

"He may have been joking, but this could be a huge hint dropped by Prince William,"  said Alex Apati of Ladbrokes, "and at this stage we're taking no chances."

Despite, William's comments, punters still believe the pair will be welcoming a baby girl, with Alice and Mary the favoured monikers at 5/1. And while Jack might be the "biggest market mover" of the the past few weeks, Albert and Arthur remain the top picks at 12/1.

Royal commentators aren't so sure, however, that the Queen's grandbaby will bear the moniker Jack.

"William joked about wanting to name his baby Jack or Jackie after an Aston Villa footballer who scored a goal," Phil Dampier told The Standard, "but seriously we are talking about the fifth-in-line to the throne and a great grandchild of Her Majesty – so they will want to be respectful"

While the baby's due date has not been revealed it is believed to be imminent, with parking restrictions in place outside the Lindo Wing of St Mary's hospital, where the Duchess of Cambridge is set to give birth.

The little Prince or Princess already has their own webpage at https://www.royal.uk/baby which promises to provide updates on the royal bub as they become available.
