Princess Diana Once Consulted Photographer Anwar Hussein About Interfaith Marriage

Princess Diana's marriage to Prince Charles was far from the fairytale romance she and the public had hoped for, but when the royal couple separated, she finally got her chance at love.

Her relationship with Dr. Hasnat Khan, a heart surgeon, is thought to have been the princess' greatest love story, even though it wasn't a well-documented one (per Vanity Fair).

It was such a great love story, in fact, that it sounds like the princess was seriously considering marrying Khan.

Anwar Hussein, a photographer who documented Princess Diana's life for her last 17 years, was on a flight with the princess in the mid-'90s when the royal approached him with some questions.

"All the lights were dimmed on the flight, and she came and whispered, 'Can I have a chat?'" Hussein tells People. "She knew that I was married to an English girl, Caroline. She wanted to know about Islam. She was asking about being married when one person is Muslim and another is Protestant.

"She was interested because of what she was going through with Dr. Hasnat Khan. She didn't mention him, but she assumed I knew it. I think she was wondering how the family would react to him and things like that."

Unfortunately, the romance ended not long before Princess Diana's untimely death. Her next boyfriend, Dodi Al Fayed, was in the car with her and also tragically passed away.

Hussein spoke to People to promote his current exhibition Princess Diana Exhibition: Accredited Access, open in Los Angeles and Chicago and coming soon to New York City.
