A new book on Eric Clapton claims he had a thing for Princess Diana.

In Motherless Child: The Definitive Biography of Eric Clapton, author Paul Scott writes, “They had first been introduced backstage at a charity concert for Prince Charles‘s Prince’s Trust at Wembley Arena in June 1987. Clapton later cringed that he had rather presumptuously addressed her as ‘Di’. For her part, the princess didn’t bat an eyelid.”

Meanwhile, a friend of both Clapton and Lady Di says there was “a lot of winking and overtly steamy looks. A story went around that one time when she and Eric were both at [a London restaurant], Diana began sucking suggestively on a piece of ice as she gave him the eye. Everyone loved that.”

Princess Diana died in a 1997 car crash in Paris. In February 1998, Clapton told us that the song “You Were There,” from Pilgrim, was, in a way, inspired by her death. He recalls it as being “like a compilation of feelings that go back to every loss I’ve ever experienced.”

Clapton said he actually wrote the song for his manager, Roger Forrester. They worked together for more than 25 years and then parted ways in early 1999.
