Betting has been suspended on the date of the birth of Meghan Markle's baby after a flurry of bets on the new Royal already being here.
Paddy Power say a rise in the number of bets on the birth of the Duchess of Sussex's baby on Thursday evening.
A spokesman said this indicates "someone knows something and perhaps the child is already born".
The bookmaker also believed the baby is a girl, and the most likely names are Diana (3/1), though Grace (7/1) Allegra (8/1) and Alice (10/1) have all proven popular this week.
"We’ve suspended betting on which day Harry and Meghan’s baby will arrive following a huge increase in wagers this evening which indicate to us that someone knows something – and perhaps the child is already born," a spokesman for Paddy Power said.
"That, combined with the rumours and speculation has us convinced that the royal arrival has already happened and if the betting is anything to go by, it’s almost certainly a baby girl."
Buckingham Palace today denied the baby had already been born.
The royal couple have broken from royal tradition and kept all details surrounding the birth a secret.
Unlike Princess Diana and the Duchess of Cambridge, Meghan will not introduce her baby to the world on the steps outside hospital hours after giving birth.
