Tycoon Donald Trump has attacked ROSIE O'DONNELL in his new book THINK BIG AND KICK ASS - calling the U.S. TV personality a "loser". The pair have been feuding since Trump's appearance on O'Donnell's former show The View earlier this year (07), which turned nasty. They have bickered in the media ever since - and the billionaire has turned to his literary effort, in a bid to have the last word. He tells the New York Post's gossip column PageSix, "I devote some time to Rosie in my book, as you know, she said I went bankrupt and ABC apologised. 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." But Trump isn't the only one committing his thoughts on the feud to print. In her new book Celebrity Detox, O'Donnell calls Trump "a torn scarecrow" and "a slug".
