Katie Couric metPrincess Diana when they were seated together at a luncheon in June 1996.- Couric said Diana told her she was "going home to an empty house" after the US trip.
On the day she met Princess Diana, Katie Couric was struck by her beauty and "girlish charm."
But when she spoke to the princess, Couric said she "sensed a deep sadness" in Diana.
Couric revealed new details about their encounter in her memoir, "Going There," which was released on Tuesday.

"At one point she turned to me and said, 'I like your lipstick,' which took me by surprise." Couric continued. "I was flattered that she'd noticed."
Couric said she later asked Princess Diana if she was "excited to go home" after such an exhausting trip in the US.
"I would be, but I'm going home to an empty house," Princess Diana told her.

"Princess Diana cocked her head quizzically at the idea of it, like a dog hearing a high-pitched whistle," Couric recalled. "At the time, I had no idea how miserable she really was."
Couric said Princess Diana also sought parenting advice during their chat, asking: "How do you keep your children from watching too much telly?"
Diana told Couric she was having a "terrible time" getting
