Prince George has a naughty Christmas trait that makes him behave like Princess Diana

Five-year-old Prince George has been known for his cheekiness, and it turns out he's inherited a naughty habit that Princess Diana used to do at Christmas time.

With regards to celebrations, the Royals are known to adhere to the German tradition, as revealed by former royal chef Darren McGrady, as reported by Mirror.

They usually open their gifts on Christmas Eve. However, little George has been spotted diving into his presents on Christmas day.

"I rushed home to open your Christmas present, which I thought was quite good considering the 25th is actually two weeks away!" Diana wrote.

In a 2016 interview with KISS FM AJ King, Prince William revealed that the little prince was caught in the act unwrapping his gifts because he was so excited.

"He said they were all really excited about it and that George is already opening his presents," King said. "He thought it quite funny."

"That's kids for you, even the ones that are princes!" the host added.

According to Mirror, George inherited the habit from his late grandmother Diana who was also known for sneaking her gifts early.

The People's Princess once confessed about it in a letter she wrote to Janet Filderman, her beautician, on December 14, 1985.

"I rushed home to open your Christmas present, which I thought was quite good considering the 25th is actually two weeks away!" Diana wrote.

"I could not resist opening my present, as a parcel of any shape or form has never been safe with me. I fear that William has also picked up this dreadful habit from his mother, as I find wrapping paper undone in the most extraordinary places!"

Meanwhile, this year will be Meghan Markle's first Christmas as an official member of the royal family, and it seems that she will also have to get used to the tradition.

It has been reported that the Duchess of Sussex's mother, Doria Ragland, will also spend her Christmas with the Royals.

On Christmas day, the royal family will celebrate early with not one but rather two church services in only three hours.

The Queen will take the communion during the first service, which is a private one for the family. It will take place at 9 am.

The entire royal family then return home to change their clothes before the public service at St. Mary Magdalene Church at 11 am.

George may go to his first service this year because royal tots usually join when they reach the age of five.
