Britain's Duchess of Cornwall wants Prince George to call her "GaGa".
Camilla ? who has five grandchildren from Tom Parker Bowles and Laura Lopes, the two children she had during her first marriage to Brigadier Andrew Parker Bowles ? thinks the royal tot will adopt the bizarre nickname for her because it rolls off the tongue better than "step-grandma".
Asked what she will call herself, she told the MailOnline, "That's something we have got to have a think about. We haven't decided yet.
"My own grandchildren call me GaGa. I don't know if it's because they think I am! It is funny but is still very sweet."
While Camilla discussed her favourite nicknames, her husband Prince Charles was at the Sandringham Flower Show in Norfolk, east of England, where people were bestowing gifts on him to give to the two-week-old baby, including cuddly toys, books and cute outfits.
Charles said, "It's a wonderful feeling [to be a grandfather]. It's a very nice feeling, isn't it?"
He also revealed plans to enrol in a babysitting course to learn how to care for George.
