She was photographed sipping an alcoholic beverage over the St. Patrick's Day weekend, but that still hasn’t put an end to the speculation and rumors that Kate Middleton could be preparing to welcome a fourth child with Prince William.

Despite sipping on a pint of Guinness during a visit to a St. Patrick's Day parade when she and Prince William headed to Hounslow to meet 1st Battalion Irish Guards at the Cavalry barracks, odds are still high when it comes to royal fans betting that the Duchess of Cambridge will announce a fourth pregnancy in 2019.

According to Bookmakers Coral, the odds have been cut yet again on Middleton potentially announcing another pregnancy in 2019, and are now at odds-on at 1-4.

“We are being knocked over with bets on Kate Middleton announcing she is expecting her fourth child which is now long odds-on in the betting on the back of this gamble,” Coral’s John Hill told Express UK.

However, there is some caution that an announcement likely won't happen soon considering the fact that Middleton sipped on a beer over the weekend, since drinking alcohol is forbidden when a woman is pregnant—and she herself abided by that same rule during a visit to the area last year, when she was pregnant with Prince Louis and sipped on a water instead.

Drinking alcohol has long been a way for members of the royal family to refute claims of pregnancy, and a similar incident temporarily quelled rumors that Meghan Markle was pregnant last summer. She was also spotted sharing a pint of Guinness at the time with Prince Harry, as well as drinking champagne, which she wouldn’t have likely done if she was pregnant.

Of course, the Duchess of Sussex conceived her first child with Harry not long after that, as the couple announced they were expecting their first child in October. That baby is expected to be born at some point in April.
