Kara DioGuardi Kara DioGuardi

Former American Idol judge and songwriter Kara DioGuardi's memoir, A Helluva High Note: Surviving Love, Life and American Idol (out April 26), reveals its author as a survivor of sexual trauma, according to E! Online. Among abuse experiences are:

- DioGuardi writes that she was molested at 11 by the son of a friend of the family in his late teens.

- Around 2000, she was raped by a "fairly known producer," after a dinner she shared with him. She says she told him to stop, but never told anyone after the fact for fear of how it would affect her burgeoning music career.

- Some time later, she was harassed by a "hugely successful artist" during a songwriting retreat. During the three-day getaway, she was exposed to pornography and strippers performing sex acts. She says she was chased around the artist's basement and eventually forced to fondle him.

DioGuardi also discusses her highly personal reason for leaving Idol: "I wanted a child, and there was no way I could get pregnant under the stress of eighteen-hour work days and live TV," she writes, adding, "I had undergone three unsuccessful rounds of IVF during Season 9."
