Kate Middleton, reportedly, dropped a subtle clue that she was pregnant with Prince George even before the palace made the official announcement years ago.

During a royal engagement, Middleton raised a toast with a glass of water instead of a glass of wine. According to Daily Beast columnist Tom Sykes, this is quite an unusual move for members of the royal family.

Back then, the Washington Post also wrote an article about Middleton’s royal engagement and said that she looked as though she was sporting a growing baby bump.

In the op-ed piece, the columnist explained that they’re acting a bit overexcited over Middleton’s pregnancy out of nothing but love for her and Prince William.

Days later, the palace announced that Middleton was expecting her first child with Prince William.

The subtle clue that Middleton dropped years ago stuck with royal fans who immediately noticed when the future queen consort refused to drink alcohol during her trip to Ireland. Shortly after, it was announced that Middleton was pregnant with Prince Louis.

Last month, body language expert Judi James said that there are several telling signs that Middleton could be expecting baby number four. The expert looked at a recent photo of Middleton from one of her engagements and said that there are at least four telling signs that she could be pregnant.

First, James said that Middleton touching her abdominal area could be a telling sign that she’s expecting. Even though the gesture is common for pregnant and non-pregnant women, James said that it is the way that Middleton placed her hand flat on her stomach that suggests she’s pregnant.

James also said that Middleton and Prince William engaged in mirroring gestures. At one point, Prince William also placed his hand on his stomach, which signals that his wife could be expecting.

The body language expert also said that Prince William’s smile is another telling clue that his wife is pregnant. After all, he seemingly suppressed a smile that he does when he’s delighted or trying to hide something from royal fans.

James also said that the fourth clue has to do with Middleton’s decision to stand behind her husband during the engagement. They are also leaning towards each other a bit, which shows how protective the Duke of Cambridge is towards his wife.

But despite James’ analysis, an entire month has passed and the palace still hasn’t announced that Middleton is pregnant with baby number four.
