Kate Middleton reportedly dropped another distinct clue that she pregnant – and not just with one but two babies.

On Monday, Prince William arrived in Oman for his four-day royal engagement, but he wasn’t joined by his wife. According to New Idea, the Duchess of Cambridge’s absence from the royal tour may have to do with her rumored pregnancy.

In the past, Kate Middleton also skipped some royal engagements and duties because she was pregnant with Prince George, Princess Charlotte, and Prince Louis. And since the mom of three suffers from extreme morning sickness, she usually stays at home during her first trimester.

The Center for Disease Control and Prevention (CDC) also identified Oman as one of the countries with an ongoing malaria risk. CDC recommends pregnant women to avoid visiting the country.

Last month, speculations regarding Kate Middleton’s pregnancy heightened after she also pulled out of the Tusk Conservations Awards with Prince William. A spokesperson from Kensington Palace announced that the future Queen won’t be able to attend the event because of her children. However, they did not elaborate on the real reason behind the absence.

And just last weekend, New Idea also claimed that Kate Middleton is pregnant with twins. The delightful news allegedly surprised the Duke and Duchess of Cambridge because they didn’t want to grow their family further.

“But the fertility gods obviously had other ideas! Now they’re praying Kate won’t be stricken with debilitating morning sickness that plagued her other pregnancies and even landed her in hospital,” a source told the publication.

The insider also said that the arrival of Prince William and Kate’s babies is exactly what Queen Elizabeth needs at the moment because of the ongoing issues within the royal family.

But the palace has not yet commented on Kate Middleton’s pregnancy and the various claims made by the publication. Confirmation of royal pregnancies come from the palace, which means that everything else should be taken with a grain of salt.
