Since their arrival from the recent royal Pakistan tour, Prince William and Kate Middleton have been busy attending several engagements. But, while the success of these events has been widely shared by the media, other reports have centered on the royal couple's current status in terms of their family.

As it happens, many are convinced that the duke and duchess are expecting their baby number four.

The pregnancy rumors seemingly started amid their recent tour in the Middle East. As per sources, the Cambridge couple traveled with their "personal doctor" in every trip they had during and after Pakistan tour.

Royal fans and supporters noted that this is a very unusual dynamic for Prince William and Kate Middleton. So, the most logical explanation behind this is that the duchess might be pregnant.

No further evidence was deemed to support the speculation during that time. However, these past few weeks became more interesting since many have noticed certain signs that are likely hinting to the Duchess of Cambridge's fourth pregnancy.

According to Cheat Sheet, Kate Middleton attended an event last week at a "children's hospice" in Norfolk. She was deemed stunning and "gorgeous" as ever. But, her attendance in the event further strengthened the speculations about her rumored pregnancy.

As per claims, it was the same event that she and Prince William attended during her previous pregnancy. The same is also true for the Royal Variety Performance held at London's Palladium Theatre.

The Duke and Duchess of Cambridge attended the said event earlier this week. It was said that this holds a "special place" to the couple's heart, especially to Kate Middleton.

The reason being is that they also attended the same event in 2014 and 2017, which were said to be the time when they were expecting Princess Charlotte and Prince Louis, respectively. Accordingly, seeing the Cambridge couple, once again, in the said event made a lot of people wonder if Kate is truly pregnant.

Other royal fans also noticed the changes in Kate Middleton's appearance, especially her hairstyle. While some seemingly "criticized" her look that night, avid followers mentioned that the duchess always introduces new changes in her appearance every time she is pregnant.

With these points at hand, it is no wonder why many are theorizing that Prince William and Kate Middleton are now expecting their fourth baby. Even so, no confirmation has been made yet from the Cambridge couple and the Kensington Palace.

In the end, however, it is still possible given that the Duke and Duchess of Cambridge have expressed their wishes of having a new baby now that their three kids are all grown up.
