Quinn, citing a royal source close to the Prince and Princess of Wales, revealed the nicknames in his book Gilded Youth.

According to the book, Prince William calls Kate Middleton ‘babykins’, and the Princess calls him ‘babe’.

The Cheat Sheet, quoting the book, says but when Prince William teases Kate about her long, full hair, she quips back and calls him “baldy.”

Quinn also disclosed Kate Middleton’s nickname that started as a gentle dig by Queen Elizabeth II.
