Prince William and Kate Middleton’s children - Prince George, seven, Princess Charlotte, six, and Prince Louis, three - nickname senior members of the Royal Family. The young royals know everything about 'Granny Diana' and refer to the Prince of Wales as 'Grandpa Wales'.

       When it comes to Camilla, who married into the family in 2005, they do not address her as 'Grandma'.

       According to the Sun, Camilla told Lady Gaga that her step-children called her 'GaGa' when they met during the 2016 Royal Variety Performance.

       Camilla is “expected” to significantly influence her step-grandchildren’s lives once Prince Charles ascends to the throne.

       According to a royal commentator, Camilla will eventually become queen consort and take on more responsibilities.

       The Talko's Natalie Rankin said she will help train the young royals for their future roles.

       She said: "Senior members of the Royal Family like Princess Anne and Camilla will be expected to increase their duties until Kate and William's kids are old enough to take on royal roles of their own.

       "George, the seven-year-old future king, is in for a life of training.

       "He will prepare to hold the highest position in the land.

       "With this, Kate will have to be super involved with his life."
