Before she became the People's Princess, Diana worked as a nanny. Her salary was $5 an hour. Back in 1980, Mary Robertson was an American businesswoman living in London and she needed a nanny for her toddler son, Patrick.

Mary had no idea the shy and quiet Diana was actually Lady Diana Spencer, an aristocrat from one of England's oldest families. #InsideEdition
