Kara DioGuardi reveals she was molested as a child, date-raped by music producer in new memoir

Kara DioGuardi claims she was molested, date-raped and sexually harassed in her new memoir.

Those looking for "American Idol" gossip in Kara DioGuardi's upcoming memoir will find some serious subject matter alongside talk of the hit Fox series.

According to E! Online, DioGuardi's "A Helluva High Note" – on sale April 26 – details the molestation she suffered as a child and her experiences with date rape and sexual harassment years later.

The former "Idol" judge claims she was repeatedly assaulted at age 11 by the teenage son of a family friend.

"On one particular day, he took me into the back shed of his house and put his hands all over my breasts and vagina," she reportedly wrote. "I remember freezing and not knowing what to do."

Years later, a "fairly known producer" in the music business allegedly assaulted DioGuardi after they shared a platonic meal together.

"[W]ithin a few hours, he was on top of me, pumping, sweating, and speaking to me in Spanish, not a word of which I could understand," she wrote, adding that she feared he'd become violent if she tried to stop him.

And a few years later, the songwriter, now 40, reportedly found herself in another unwanted, sexually-charged situation when a "hugely successful artist" invited her on what was supposed to be a work-related trip.

 "The trip's activities," ended up consisting "of watching Russian porn, scavenging around the kitchen for food [and] leering at two strippers ... as they performed sex acts in the living room."

DioGuardi initially didn't want to "let this bastard deter me from doing the job," but eventually stopped working with him once the harassment escalated on a future occasion.

As for "Idol," DioGuardi claims her two-year stint on the show directly correlated to her inability to get pregnant.

"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 reportedly wrote, a lesson she learned after going through "three unsuccessful rounds of IVF during Season 9" in 2009-2010.

So when DioGuardi heard her job might be on the chopping block, she said she asked to be let out of her contract.

That hasn't deterred her from returning to TV next month on Bravo's upcoming reality series, "Platinum Hit." The show, which premieres May 30, is a songwriting competition with DioGuardi appearing as "head judge" alongside country singer Jewel.
