Kate Middleton will most likely announce her fourth pregnancy before the year ends.

According to bookmakers Ladbrokes, the odds-on for the Duchess of Cambridge to announce another royal baby is on 8/11. Alex Apati, the spokesperson for Ladbrokes, spoke with Express regarding the possibility of Middleton adding another member to the Cambridge family.

“Will and Kate adding to their family is seemingly inevitable and according to the latest odds we could soon be welcoming another royal baby into the world,” he said.

Throughout the past couple of months, eagle-eyed royal fans have also been convinced that Middleton is dropping signs that she’s pregnant. For instance, she sometimes touches and carries her abdominal area.

When Meghan Markle did the same gesture two years ago, the palace announced shortly after that she’s pregnant with her son, Archie.

Body language expert Judi James told Express that Middleton cannot possibly be pregnant right now. After all, she suffered from extreme morning sickness during her first three pregnancies.

As such, if the Duchess of Cambridge is pregnant, she wouldn’t be able to make appearances both in public and via a video call.

James said that touching the belly is a more common indication that Middleton could be expecting. However, since she does this gesture regularly, royal fans shouldn’t also see the gesture as 100 percent accurate.

The body language expert acknowledged the fact that Middleton's pregnancy is the hardest to spot. After all, her body language doesn't necessarily change when she's pregnant or not. 

“She will often leave her coat hanging open she won't use the rubbing gestures that Meghan was so famous for. For a lot of royal women traditionally, it is business as usual,” she said.

Some royal experts are also convinced that Middleton will announce her fourth pregnancy soon because of the age gap of her kids, Prince George, Princess Charlotte, and Prince Louis.

Prince George was 2 years old when Princess Charlotte was born. And the 5-year-old was around 3 years old when Prince Louis was born.

The youngest child of the Duke and Duchess of Cambridge just turned 2 years old. Which means that a fourth child may already be in the works.

According to royal expert Phil Dampier, Middleton and Prince William also have more time with each other because of the coronavirus lockdown. He told New Idea that he wouldn’t be surprised if the couple will announce Middleton’s pregnancy after the pandemic is over.
