In her new memoir, A Little Thing Called Life, Caitlyn Jenner's second wife, actress-lyricist Linda Thompson, reveals that Jenner wanted to transition to female in 1985.

Jenner came out transgender last year and went on to star in the recently canceled I Am Cait reality series.

Thompson writes that Jenner (then known as Bruce) came out to her in 1985.

“I have lived in the wrong body my whole life,” she said that Jenner told her. “It is a living hell, and I really would like to move forward with the process of becoming a woman.”

“Bruce told me he was considering traveling out of the country, possibly to Denmark, to try to have the gender reassignment surgery anonymously and then come back as a female,” Thompson wrote, adding that Jenner wanted to re-enter their two sons' lives as a female relative.

The couple divorced the same year.

Thompson said that she felt an obligation to keep quiet about Jenner's gender issues.

“I felt such an obligation to keep Bruce's gender dysphoria his secret that I did not even tell my sons until they were 31 and 29 years old, respectively,” she wrote.
