The news was a bit of a shock for Presley, who was in the process of getting divorced from then-husband Danny Keough, the father of her daughter, actor Riley Keough, who co-wrote the memoir.
Jackson ― who was 10 years older than Presley ― first met her when they were much younger, before reconnecting in the early 1990s.
Although she was still married to Keough, the couple split amicably after Jackson confessed his love during a trip to Las Vegas.
