After canceling her appearance at the Tusk Conservation Awards in Leicester Square last week, Kate Middleton is reportedly not joining the next royal tour of her husband, Prince William. The Duke of Cambridge will be going solo as he visits Kuwait and Oman next month. So, why does the Duchess of Cambridge can't make it?

The past few months had been very busy for the Cambridges. Their recent visit to Pakistan was deemed to be a huge success. Kate Middleton was even said to be Prince William's huge asset when they went to the said country.

According to Express, a lot of people praised their time in Pakistan. Even her style and fashion were admired across the globe. However, there are reports Kate Middleton will not be with Prince William when he goes to the Middle East.

An official statement from Kensington Palace confirmed that Prince William would embark on a solo trip. "The Duke of Cambridge will visit Kuwait and Oman between Sunday 1st December and Wednesday 4th December," it read. "This visit is at the request of the Foreign and Commonwealth Office, and will be His Royal Highness's first official visit to both countries."

The second in line to the throne's next visit is reportedly at the request of the British Government. He will be in Kuwait and Oman for four days, starting on Dec. 1 until Dec. 5. Kate Middleton, on the other hand, will stay at home with their kids, Prince George, Princess Charlotte, and Prince Louis.

During term-time, the family reportedly moves to Kensington Palace in London. Hence, Kate Middleton may want to stay with their children before the Christmas holidays take place. This is the time when they have to leave their Norfolk home, Anmer Hall.

Prince George and Princess Charlotte will soon have their Christmas holidays break from St George's school in Battersea. So, their mother may want to be there for their kids. She may want to prepare for the festivity even before her two eldest children stay at home for the Christmas vacation.

This is not the first time that Kate Middleton will be a no show at an important event that Prince William has to attend to. To recall, she was reportedly forced to cancel attending the Tusk Conservation Awards because of her children, too.

Business Times recently reported that it wasn't revealed what happened to Kate Middleton and Prince William's kids, but she reportedly has to stay with them. Sources also didn't give any details about the matter.
