Rosie O’Donnell’s opening her giant pie hole (and cake hole, and nachos hole, and pizza hole) again, but this time it’s about something we like to hear…her beating herself up.

Although it is her unkind treatment of former employer Barbara Walters in the pages of Rosie O’Donnell’s upcoming memoir, Celebrity Detox, that has been generating headlines, the former "Queen of Nice" also bashes herself in her book – literally.

As a child growing up on New York’s Long Island, O’Donnell, now 45, would fracture her own limbs with "a baseball bat" or a "wooden hanger," she reveals in the book, reports The Insider.

In the excerpt, first revealed in Roger Friedman’s FoxNews.com column, O’Donnell writes that in choosing what to break she’d go for "My hands and fingers usually. No one knew. My secret."

Seeking to explain her motivation for the self-destructive act, she reportedly writes, "Proof that I had some value, enough to be fixed."

She adds later, "There were many benefits to having a cast. In the middle of the night, it was a weapon." Why she would need a weapon in the middle of the night is not addressed, Friedman reports.

Perhaps it was to fight off the bed bugs that fed off her fat…just a thought.
