The Duke and Duchess of Cambridge are under the scrutinizing eyes of the public at all times. For this reason, some cannot help but notice Prince William's noticeable absence when his wife attended the Action on Addiction Autumn Charity Gala earlier this week.

Several reports are claiming that Prince William and Kate Middleton are fighting behind the scenes. Middleton, whose current condition is delicate, is reportedly staying with her mother. She allegedly does not want to return to Kensington Palace.

The palace, however, is yet to comment about the reports. The rumors likewise do not shed light to the reason behind the marital stress. One source told Celeb Dirty Laundry:

"Exclusive sources provided an update and unfortunately tell us that Kate Middleton and Prince William are still fighting, and that Kate didn't want to return to Kensington Palace just yet. Sure, the royal couple just made two public appearances together earlier this week, and were the picture of a loving and dedicated couple, but they're also pros at this - they have had years and years of practice, and I'm sure they can turn on a fake smile and pretend for the cameras."

It can likewise be noted that Middleton staying with her mother does not necessarily imply a feud between the two British monarchs. With Middleton battling severe morning sickness, she might find it more comforting to be taken care of by her mother.

Meanwhile, a palace insider recently refuted reports of Middleton carrying twins. One reason is that the two's family trees do not have history of twins.

Nonetheless, it has been confirmed that her due would be in April 2015. One insider tells People magazine that Prince George's mother is still ill but is "definitely recovering."

"She was her smiling, bubbly self. You would never have guessed she's been ill," said the informer.
