Newly minted movie star Jennifer Hudson is biting the hand that fed her -- charging she was "abused" and "brainwashed" by "American Idol."

"On 'American Idol,' you go through this mental thing; you've got to get yourself back together," she says in the March issue of Essence magazine, according to an excerpt published by People.

"You've been abused, misled and brainwashed to believe whatever they want you to think."

Those are strong words from Hudson, who owes her big break to "Idol," on which she appeared as a contestant in 2004.

She's now a favorite to win an Oscar after being nominated as Best Supporting Actress for her role in "Dreamgirls."

Hudson, 25, also tells Essence that "Idol" unfairly branded her.

"You become a character -- I became the girl in the turkey wrapping," she says, alluding to an unflattering outfit she wore on an "Idol" episode.

"I just knew I had to sing my way out of it," she says.

Hudson was voted off the third season of "Idol," then brought back in a wild card round and eventually made it through to the finals.

Fantasia Barrino ended up winning that season.

In the Essence interview, Hudson also comments on her alleged feud with "Dreamgirls" co-star Beyonce Knowles.

"We clicked from day one," she says.
