Actresses Anne Heche and Ellen De Generes began dating in 1997, soon after De Generes publicly came out.
They dated until 2000, when they had a reportedly tough breakup.
Her brother Nathan died in a car crash aged 18 in June 1983.
Her sister, Susan Bergman, died aged 48 in January 2006.
Since her husband's death from AIDS, Nancy Heche has been a Christian therapist and motivational speaker.
She lectures on behalf of James Dobson's Focus on the Family about "overcoming" homosexuality.
On August 19, 2000, Heche drove from Los Angeles to Cantua Creek, a rural area outside Fresno, California. Wearing only a bra and shorts, Heche walked 1½ miles through the desert before knocking on the door of a stranger's ranch house.
When the home's resident, Araceli Campiz, opened the door, she knew Heche from the movie Six Days Seven Nights.
