Rumors of Queen Elizabeth and Kate Middleton not getting along very well have been circulating even before the Duchess of Cambridge married Prince William.

And now, it seems that the Duchess of Cambridge's personal relationship with the Queen is getting worse, all thanks to Kate Middleton's mother, Carole who has allegedly been backing her up to defy Queen Elizabeth.

It has earlier been reported that Carole Middleton has been assuming a big role in raising Prince George and Princess Charlotte.

"You can call Carole Middleton a social climber and sycophant, but she does not give soggy crumpet what anyone thinks - even the Queen," Celeb Dirty Laundry wrote. "Carole, once an airline flight attendant, is clearly having the last laugh. Thanks to her position in the Duke and Duchess of Cambridges' lives, Carole is shaping the values and personality of the future monarchs, Prince George and Princess Charlotte."

"Carole and Kate have instituted a new regimen that favors family and middle class values instead of privilege. Make no mistake, the Middletons and royal enjoy the power and riches of a multi-million dollar allowance, but Carole and Kate call the shots. Anmer Hall is lavish country home, but the Middleton family dominates, constantly making changes to royal traditions and protocol."

Kate Middleton's mother not having a care about what Queen Elizabeth thinks about her is confirmed by The Daily Beast's source.

"Carole is untroubled by self-doubt," a friend reportedly said. "She couldn't really care less if people think she is an arriviste or a social climber. Her focus is all about Kate, William, George, and Charlotte."

Inquisitr reported that the tension between Queen Elizabeth and Carole Middleton seems to be taking its toll on Kate Middleton, with Prince William's wife "seen looking quite thin recently." Some reportedly speculate that her weight loss is connected to a "high-stress life."
