Kara DioGuardi says in her memoir "A Helluva High Note" she was date-raped by a music producer.
"He was on top of me, pumping, sweating, and speaking to me in Spanish, not a word of which I could understand," DioGuardi wrote in the book.
She added she didn't report the incident for fear it would ruin her career, UsMagazine.com said.
DioGuardi, a former judge on "American Idol," will be seen next month in the new competition series "Platinum Hit."
