In December 2014, the Duke and Duchess of Cambridge met LeBron James, the most famous basketball player in the US. Despite the fact that one of his nicknames is “King James,” he is in fact not royalty, and protocol demanded that he should not touch the Duke or Duchess. Not knowing this, LeBron put his arm around the couple and posed for a photograph. This was a shocking break in decorum for some, but the royal couple seemed comfortable and shared that they enjoyed meeting “King” James.
