Royal watchers in Eastern Canada are streaming to stores to place bets on the possible name of the newest member of the Royal Family.

The Duke and Duchess of Sussex, Prince Harry and Meghan Markle, are expecting their first child next month.

Now betting service Pro-Line is offering odds on the name, gender and birthdate of the new royal.

鈥淚t's just a fun way to give people an option to wager on something that鈥檚 of interest right now," Natalie Belliveau from the Atlantic Lottery Corporation told CTV Atlantic.

"People think it's going to be a girl and they're kind of leaning towards Diana."

Princess Diana was Prince Harry鈥檚 mother who died in a car crash in Paris in 1997.

Baby name favourites so far are Diana and Philip, with the worst odds on Theresa and George.

Aron Spidle from the Monarchist League of Canada said the royals are the 鈥渋n鈥 thing and everyone wants a piece of the action.

"They're a very young, nice, glamorous couple," he told CTV Atlantic.

鈥淓veryone can hook into that and celebrate it together, right?鈥

Derek Ross, who runs a store in Halifax, N.S., said lottery and Pro-line tickets are a 鈥済ood percentage鈥 of his business.

He believes customers will be all-in placing baby bets in coming weeks.

Wagers can be made through April 5 in store or online.
