British bookmakers have halted betting on when Meghan Markle, Duchess of Sussex, will give birth, as some speculate that the newest royal baby has already been born. 

Bookmakers Paddy Power and Coral have stopped allowing bets on the matter, according to CNN, as they saw increases in customers betting on dates that have already passed. 

"We suspended betting on the birth date last Friday as we were seeing an abnormal number of large bets on that day being the birth date," John Hill, Coral's PR manager, told CNN. He was referencing May 3, when Prince Harry quickly altered his travel plans, sparking speculation that his wife had already given birth.

"These people are clearly talking to someone, who is talking to someone else," Lee Price, Paddy Power's PR chief, told the news outlet. 

The companies said they are still taking bets for the name of the baby and have reported seeing a spike in bets that the child will be a girl named Ivy. Multiple bookmakers have Ivy as the favorite, with Alice, Diana, Victoria and Elizabeth behind it. 

"We have suspended all of our markets apart from the name of the baby, where Ivy is currently the short-price favorite on the back of a surge of bets in the last 48 hours," Hill said.

Markle, an American actress who married the U.K.'s Prince Harry last May, is expected to give birth any day if she has not already. Her mother, Doria Ragland, reportedly arrived in England late last month in preparation for the birth.

The child will be the seventh in line for the throne.
