The Mail Online reports that a popular betting site, Paddy Power, has received so many bets that the royal couple are having twins, they've stopped allowing any more to be placed.
Due to the surprising influx of bets, the company thinks a source with inside knowledge of Harry and Meghan's pregnancy may have been the first to place money on the pair having twins.
"We had to suspend betting. We saw an almost identical pattern of betting before the announcements of the couple's engagement and pregnancy," a spokesman for the Irish betting company said.
"Since the day began, the stream of bets has led us to believe that perhaps the punters - or an insider source - knows something more than we do."
So many bets were placed on Friday night, it's reported the odds were slashed from 5/1 to odds-on.
However, sadly, we wouldn't put too much thought into royal twins, as the official announcement about Meghan Markle's pregnancy said the couple were "very pleased to announce that The Duchess of Sussex is expecting a baby in the Spring of 2019."
A baby, not babies.
But hey, we wouldn't be mad if both Harry and Meghan were carrying a newborn out of the Lindo Wing next year.
