Kate Middleton and Prince William are currently in Kensington Palace practicing social distancing along with the rest of the country. While this doesn't seem extraordinary, given that the entire world is in self-isolation mode amid the coronavirus pandemic, reports about the couple expecting their fourth have surfaced online.

According to Liam Doyle of Express, the Duchess of Cambridge has been subject to pregnancy rumors since Prince Louis was born a couple of years ago. The country is hoping that Cambridges will add another member to the family soon, which means, bringing another heir to the crown into this world.

But are Prince William and the Duchess of Cambridge expecting another child? The popular couple has three children including 6-year-old Prince George, 4-year-old Princess Charlotte and Prince Louis, who is just 1 year old. Each of these kids grabs their own spot in the British succession lineup following the Duke of Cambridge.

The country is still hoping that the duo will soon welcome another child to their family - in short, another heir to the coveted throne. Amid the couple's decision to avoid public engagements, clues about the Duchess of Cambridge's pregnancy are few and far between. Nevertheless, a New Idea (via  In Touch) report suggests an insider has confirmed it will be a girl.

Kate Middleton's recent trip to Ireland sparked pregnancy rumors. The Duke and Duchess were in Dublin earlier this year citing a royal tour. They stayed in the Irish capital for three days and visited the Guinness factory, and even enjoyed a pint of the black beer.

The Duchess also enjoyed the iconic beer, indicating that she is not pregnant since expectant women usually refrain from drinking alcohol citing health officials' advice. Royal experts haven't been able to spot any other clue that hints at Duchess' pregnancy, as she has self-isolated herself in the Kensington Palace along with her family amid the COVID-19 pandemic.

The royal family has been carrying out their royal duties without stepping outside their residence, except for attending a meeting with frontline NHS staff last month. Despite the lack of clues, speculators continue to speculate about Kate Middleton's pregnancy.

According to bookmakers, William and Kate are not the only expectant couple as Meghan, the Duchess of Sussex and her husband Prince Harry are expecting another child this year. The betmakers with Coral have assigned the Duke and Duchess of Sussex 1-3 odds they will announce their second child this year while assigning the Duke and Duchess of Cambridge  9-4 odds to announce their fourth child.
