Prince Charles dated Princess Diana’s sister before her
Prince Charles dated Lady Sarah in 1977 – and only later that year he met Diana. The two even went together to a plush Swiss ski resort called Klosters during their short-lasting affair. Charles was the one who ended their relationship after he saw Lady Sarah talking to a journalist. Months after their affair ended Charles moved on to pursue Lady Sarah’s sister Diana. Lady Sarah not only approved of this relationship, she even said that she was the one who introduced them! Charles who eventually settled down with Diana dated several women for 10 years before that. He was under a lot of pressure from the media to marry already.
