May the odds be ever in your favor when it comes to Meghan Markle and Prince Harry expanding their family.

Ladbrokes Coral, a British betting and gambling company based in London, just announced that the Duke and Duchess of Sussex are now odds-on for letting the world know that Archie Harrison will get a little brother or sister by the end of 2020, according to Express. The odds, as reported by the British publication, are 1/2.

It's no secret that admirers of the royal couple would be excited if the couple decided to expand their family.

"Royal fans would be overjoyed if the Duke and Duchess were to announce they're soon to hear the pitter-patter of tiny feet once again, and for Archie to become a big brother," Ladbrokes' Jessica O'Reilly shared.

The odds-on announcement comes after Harry and Meghan made their Remembrance Day appearance. During a visit with a group of military wives and their kids in Windsor, Prince Harry seemed particularly intrigued by how their families adjusted to having a second child. Perhaps, a hint that he was preparing to do the same.

"Harry was quite interested in how things were with second children as well because we’ve both got older children," Susie Stringfellow told the Forces Network of her conversation with the Duke.

"We were trying to encourage him to have a second baby," she added.

If Meghan and Harry do announce a second pregnancy before the year is over, it's likely that it will be while they are in the U.S. As previously reported, it's being speculated that the royal family will spend the holidays away from the other members of the British royal family. Starting with Thanksgiving in Los Angeles where Meghan's mother, Doria Ragland lives.
