Sarah Palin Knocks Levi, 'American Idol'

Sarah Palin
Sarah Palin isn't done with Levi Johnston. And she's also not crazy about "American Idol."

The former Alaska governor and Republican vice presidential candidate writes in her new book that it was "disgusting" to watch the estranged father of her grandchild exploit his sudden fame after she was chosen as U.S. Sen. John McCain's running mate in the 2008 election.

Palin also has words for "American Idol," writing about contestants she finds untalented and suffering as "victims of the cult of self-esteem."

Palin's new book is called "America by Heart." It's billed as a celebration of American values. It's not out until next week, but pages were posted Wednesday on the blog Palingates.

Johnston said last month he wasn't doing any more interviews for a while.
