Kate Middleton and Prince Willam should have another baby girl, according to the netizens.

For months, there have been rumors that the Duke and Duchess of Cambridge are already expecting their fourth child. The palace has never confirmed the speculation, but Prince William and Middleton’s supporters are hoping that the rumors are true and that they are having a girl, so Princess Charlotte will have a sister.

“That would be wonderful if she is, i hope so,” a royal follower commented on Twitter.

“Beautiful, happy couple like them should multiply!!! If it’s true, I hope it is, I wish it will be kind to her,” another user wrote.

“IMO they’re not sticking with three and I hope its a sister for Princess Charlotte. Time will tell,” one netizen tweeted.

A different netizen is convinced that Middleton is pregnant because she noticed some changes in the duchess.

“I think she is. The blue coat she has on the other day shows a hint of a bump and she’s been putting her hand on her tummy. Also, she changed her hair. #katemiddleton #cambridgebaby,” the online user wrote.

A few weeks back, Prince William was photographed accompanying Queen Elizabeth II on the way to Crathie Kirk for a Sunday service sans Middleton. According to an insider, the duke made a surprise visit to Scotland to inform the Queen that they are expecting another baby after Prince Louis.

The betting for Prince William and Middleton welcoming another baby soon has been suspended after the bookmakers received a flurry of waves following Middleton’s public appearances. Many are convinced that the Cambridges are likely to welcome their fourth baby in 2020.

Meanwhile, body language expert Judi James also shared her opinion about the rumors that Middleton is expecting. According to her, the duchess has been dropping more pregnancy clues.

Middleton communicates eloquently and she is taking a more dominant and sociable role which could be hinting at “another pregnancy.” Also, the duchess has been seen touching her belly — a common gesture of protection pregnant women do in the early stages of their pregnancy.
