Prince William and Kate Middleton are already proud parents of three young children, six-year-old Prince George, four-year-old Princess Charlotte, and one-year-old Prince Louis, but adding another member to their family is certainly not far from happening. The Duke and Duchess of Cambridge have always said that they are open to having a big family, so they are willing to make their family of five bigger.

With that revelation, it is only natural that the public and the press will have their eyes focused on Kate Middleton’s baby bump. Standing at 5’9 with an incredible 24-inch waist, it is very hard for the Duchess of Cambridge to hide any signs of being pregnant.

“Kate is an exercise junkie. Pippa and Kate take their toned physiques extremely seriously,” a royal insider told the Daily Mail. “And mother Carole, in her 60s, is in extremely good shape.”

So when Kate Middleton’s baby bump was allegedly spotted during an outing with her children, many assumed it was the real deal even without the confirmation of the Duke and Duchess of Cambridge and the Buckingham Palace.

New Idea shared two photos of Kate Middleton’s baby bump with the headline, “Kate Finally Confirms Baby No. 4. First Baby Bump Pics!” The Duchess of Cambridge was wearing a pink dress, and the tabloid pointed out that her abdomen looks much bigger than usual.

"Kate has seen the bond between George and Charlotte and thinks it would be lovely if Louis had a sister closer to his age,” a source said. “She is very friendly with Crown Princess Mary of Denmark and admires the way she has coped with four children.”

Now, a new report revealed that during Kate Middleton’s trip to North Ireland, where she met five-month-old James Barr, the crowd started shouting “number four.” They were talking about the Duchess of Cambridge’s supposed fourth baby.

Royal reporter Robert Jobson then shared that baby James’ dad Alan asked Kate Middleton about her being pregnant with baby number four, she responded, “I think William would be a little worried!” Since her reply is quite vague, it is hard to tell if she just confirmed the pregnancy rumors or denied it.

For now, these Kate Middleton baby bump rumors remain as that — just rumors. Until Prince William, his wife, the Buckingham Palace confirm the pregnancy speculations, these stories are considered just mere speculations.
