Cher released the first installment of a planned two-part memoir Tuesday, “Cher: The Memoir, Part One,” spanning roughly the first half of the 78-year-old entertainer’s life, with anecdotes about a marriage to Sonny Bono she called “ loveless ” that led her to consider suicide at the height of their television fame in the 1970s.

Though Cher and Sonny Bono’s marriage lasted less than a decade, their musical hits endured. Yet Cher details in her new memoir that the success of her creative partnership with her late husband wasn’t equally shared.

Under a section titled "Author's Note," Cher wrote that the book, "Cher: The Memoir, Part One, " is based on her "sometimes imperfect" memory, and then mentioned her son Chaz Bono, whom she share d with her late ex-husband Sonny Bono.
