Prince Charles and Camilla Parker-Bowles were noticeably absent on Prince William and Kate Middleton's son, Prince George's birthday, and while the reason given was they had "prior engagements," it was only half the story.

According to Globe magazine, as shared by Celebrity Dirty Laundry, Prince William and Kate Middleton purposely didn't invite Camilla Parker-Bowles to Prince George's second birthday.

The reason? Prince Charles' wife reportedly embarrassed herself during Princess Charlotte's christening.

The British tabloid claimed that Camilla Parker-Bowles invited herself to the christening, even if Prince William and Kate Middleton banned her from attending.

Once at the ceremony, the report added, Prince Charles' wife immediately went to the bar and drank herself to near stupor.

The source alleged, "Camilla couldn't be contained. In a sudden outburst she accused the royal family of trying to push her out and vowed 'You will never get rid of me if you don't pay!'"

"And that was the end of the party. Everyone started to leave, muttering their thanks for such a lovely day. The truth is Camilla wrecked Charlotte's christening!"

CDL noted that there must be truth to the rumor because Prince Charles and Camilla Parker-Bowles could have easily rescheduled their engagements to attend Prince George's second birthday.

Globe earlier claimed that Camilla Parker-Bowles was cheating on Prince Charles with two lovers, and the couple is on the brink of a $400 million divorce.

However, the son of the Duchess of Cornwall, Tom Parker-Bowles, denied all the rumors surrounding Camilla Parker-Bowles and Kate Middleton. The two women are reportedly at odds over the latter's insistence to shed off some of the royal protocols in raising her children.

In an interview with Daily Mail Australia, he said, "They get on fine. I don't think there's any truth to [the rumours of tension]. Well, I can't guarantee for sure, but I think that's all bulls**t."

Tom said that Camilla Parker-Bowles was very fond of children and would dote on Prince William and Kate Middleton's kids.
