Eric Clapton's ex-wife LORI DEL SANTO is writing a book about the loss of their son CONOR. Four-year-old son Conor tragically fell to his death from the 53rd floor of a New York City skyscraper in 1990. The couple were so traumatised by the loss of their child, they separated not long afterwards. And now Del Santo is determined to write a book about the events following Conor's death, after discovering a diary she kept at the time. Del Santo says, "The autobiography will be about what my life has really been like. It involved love and passion and my own version of what really happened that day. When the tragedy happened, I wrote 200 pages that I locked away in a safety deposit box, alongside some video footage of Conor, which I recently showed during an ABC interview with journalist DAPHNE BARAK. "It has been interesting to see how I was feeling at the time - it's a sign that I'm ready to tell the story." And Del Santo refuses to worry about what Clapton might think of her decision. She adds, "I don't care if he is happy with it or not, because he will tell his story and I will tell mine."
