Rosie O'Donnell calls Donald Trump "a torn scarecrow" and "a slug" in her new book, according to the New York Post's Page Six gossip column.

In "Celebrity Detox," which hits shelves Oct. 2, O'Donnell writes about the Tara Conner scandal — in which Miss USA was caught drinking underage but was allowed to enter rehab and retain her title.

"I honestly did not anticipate the malice of his response ... I assumed Donald believed he had money," O'Donnell writes. "I did not assume Donald believed he was money. But apparently he does ... The stuffing of his self spilled out — think of a torn scarecrow, only instead of hay, it's crisp $100 bills blowing through the cornfields."

Trump reminded O'Donnell of "garden slugs ... I could write one small comment on my blog, and Donald would predictably distend, flowing forth with a torrent of insults ... Then he'd appear on some talk show looking wrinkled, old and empty, with a Jell-O orange combover.

Trump, who has his own book, "Think Big and Kick Ass," coming out next month, responded to Page Six by saying:

"I devote some time to Rosie in my book. As you know, she said I went bankrupt and ABC apologized. Rosie lies. I got angry because I never went bankrupt. I'm worth $8 billion today. She never said that. She writes false stuff ... Rosie is a loser, a very sad case — unattractive both inside and out. I'll make a little wager my book sells a lot more than hers."

Cindi Berger, O'Donnell's representative, told Page Six, "I find it hard to believe you got a copy of this book as there were no galleys even produced. The pub date is Oct. 2." All proceeds of O'Donnell's book go to her charity, Broadway Kids.
