Her father was an equerry to QEII, both her grandmothers were ladies in waiting to the Queen Mother.
She lived on the Sandringham estate as a child and played with Prince Andrew and Prince Edward.
Her family were an established part of the aristocracy and she would have been brought up with a clear idea about how everything worked within society.
She dropped out of school at 16 because she failed her O levels - she went to finishing school like many girls of her social class.
Then she came and lived as a trust fund baby with a similar group of women doing the same thing - having fun in London, taking odd jobs like cleaning her sister's flat or working as a baby sitter - it was what a lot of the 'Sloan Ranger' set did - they didn't need to work to live because everything was paid for by their family or trustfunds.
She played tennis, took dance lessons, went on regular skiing holidays.
She might not have had any serious boyfriends but she certainly was surrounded by plenty of women who were dating.
Stop infantilising her. She was a 19-year-old woman living a fun and privileged life of the upper classes.
