Bookies are set to lose around £500,000 if the Royal baby is a girl and the Duke and Duchess of Cambridge name her Alice.
Arrangements are now in place at St. Mary's Hospital in London for Kate to give birth, possibly next week, and the public have caught baby betting fever in the hope of cashing in on the happy event.
One punter from Edinburgh has placed a mighty £2,000 on a new princess with Ladbrokes. And now stakes on the name Alice have become 'silly'.
Ladbrokes' spokeswoman Jessica Bridge said: "The support for Alice is starting to get silly now, but we've been left with no option but to cut the odds as punters relentlessly back the girl/Alice combination."
Coral's Nicola McGeady added: "Punters have gone royal baby betting mad and we have already taken tens of thousands of bets across the nation.
"Turnover has soared and in particular more and more female punters are queuing up to make their predictions.
"If the money talks, then the royal baby will be a seven-pound Princess named Alice, born sometime in the morning."
The royal couple have stayed silent about the gender and due date of baby number two, yet punters are placing their bets on Princess Alice being born between Tuesday April 21 and Monday April 27.
The odds on the name are at 5/4, followed by Elizabeth and Charlotte, both at 6/1.
If Princess Alice does become the newest member of the British royal family, industry insiders say it would cost bookmakers a breathtaking £500,000 in payouts to those who bet on the sex or name, according to The Telegraph.
