In the early 2000s, when they were both students at the University of St. Andrews, the prince would “often whisk Catherine off to Highgrove or Sandringham or to a cottage on the Balmoral estate,” according to passages from a forthcoming book, “Catherine, The Princess of Wales,” obtained by People magazine.
British author Robert Jobson stated, “They occasionally checked into hotels, using the names Mr. and Mrs. Smith, which doubtless fooled no one.”
It seems improbable that “Mr. and Mrs. Smith” served as the idea for the code names because the movie was released in 2005, the same year the Prince and Princess of Wales received their diplomas.
Still, “Mr. Smith” wasn’t William’s only alias. When he initially entered college, the royal tried to be more normal by using “Steve” as a cover in “a rather pathetic attempt to stay under the radar.” Kate kindly assisted, addressing him by the fictitious name.
