Actress Christina Haag, 50, enjoyed a five-year romance with Kennedy, Jr. in the 1980s and she recounts the special relationship she had with President John F. Kennedy's son in her memoir Come to the Edge.
She tells the Los Angeles Times newspaper, "What I was really writing about is a love story, and it happens to be with a boy I met in high school, lived with in college as roommates and then fell in love with when I was about 25.
"We were together about five years and parted. The person happens to be John. It's not a book about the Kennedy family. It's a love story and a story of friendship. I began writing in 2003... I began writing after his death just to deal with my grief. It was several years later that it was a real desire to capture that time in my life and to hold on to those memories and embrace them."
The elder son of assassinated U.S. President John F. Kennedy dated the actress for five years in the 1980s, prior to his marriage to Carolyn Bessette-Kennedy.
Haag has now recalled her time with Kennedy, Jr. in her new memoir, Come to the Edge, and in excerpts published in Vanity Fair magazine, she details a brush with death in Jamaica during a kayaking expedition.
The pair went out on the ocean without life jackets but they were plunged underwater as they attempted to make their way back to shore, and Haag was convinced she was facing death.
She writes, "This is it. This is how it ends. We are going to die together. This is what it means to drown. My lungs hurt, and as we crested a steep wave, I coughed, spat water, and clung to the edge of the boat with my head down. I waited, fully expecting to be flung backward out of the boat, but we made it over. I looked back at him, amazed, and saw that he had never stopped. He'd never given up... and we were coursing past the break to safety."
Haag also reveals that after the incident, Kennedy, Jr. was oblivious to the danger they had been in. She told him, "John, we could have died," and he replied, "Yeah, Chief, but what a way to go."
Kennedy, Jr. died in a plane crash in 1999.
