The alleged royal feud between Kate Middleton and Camilla Parker Bowles has reportedly been on-going for quite some time now.

According to previous reports, Kate Middleton and Prince William allegedly got mad at Camilla Parker-Bowles after she was purportedly caught cheating on Prince Charles. A photo of Camilla kissing a man who is allegedly her British TV star boyfriend was published in Globe Magazine and created yet another scandal putting the royal family's reputation on the line.

"William raged that this was the final nail in Camilla's coffin, and she had humiliated Charles and the royal family for the last time!" a royal insider reportedly told Globe Magazine.

"He told Kate, 'How can we trust her after this? I don't want her anywhere near George and Charlotte, she's banned!' Prince William and Kate Middleton would be happy never to set eyes on her again."

However, it seemed that the royal couple gave Camilla another chance when they invited her to Princess Charlotte's christening. However, things reportedly didn't go so smoothly during the occasion.

"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," a source reportedly told Globe Magazine.

"Everyone started to leave, muttering their thanks for such a lovely day. The truth is Camilla wrecked Charlotte's christening!"

This was reportedly the reason why Kate Middleton decided to ban Camilla Parker Bowles in Prince George's second birthday party.

"Obviously, Kate Middleton and Prince William were not giving Camilla the opportunity to ruin Prince George's birthday, too, and they forbade Prince Charles from bringing his second wife to the event," Celeb Dirty Laundry reported.

"Instead, Charles and Camilla are busy on a royal tour of the West Country. But everyone knows that they could have planned accordingly and attended Prince George's birthday party if they were actually allowed to be there."
