Rumor has it that Camilla is none too happy over the fact that Queen Elizabeth has given the Duchess Princess Diana's Tiara, the Cambridge Love Knot. It first belonged to the Queen herself and supposedly no one is to wear it without Her Majesty's permission first.

Apparently, Camilla feels like she is being rejected by the Queen as she skipped her over to give young Kate the diamond-encrusted headpiece. It was initially a gift given to Princess Diana from Queen Elizabeth on her wedding day in 1981. What's more, the tiara hasn't been seen publicly since Princess Diana died in a tragic car accident back in 1997.

Blogger Grace Gerard of Celebrity Dirty Laundry says Camilla took this as a direct insult and is allegedly drinking again because of her anger.

A royal source dished, "Queen Elizabeth has referred to Duchess Camilla as a deadly cancer to the Royal Family. The monarch also reportedly told Prince Charles that he is "feeble and has no control over his crazed wife." Queen Elizabeth also allegedly told the Prince of Wales that the future of the Royal Family 'lay in the hands of William and Kate.'

So far, Buckingham Palace has not made any comments about the report. Stay tuned with Enstars for all the latest news on the entire British royal family right here.
