Stay tuned for… "Battle of the Network Lesbians!" ELLEN DEGENERES exploded when "American Idol"-hater ROSIE O’DONNELL blasted the "Idol Gives Back" charity show – co-hosted by Ellen – which raised a whopping $70 million for poverty-stricken U.S. and African children! Ellen was stunned when Rosie – who often slams "Idol" as racist, mean-spirited and fattie-phobic – twisted her kisser into that trademark sneer and ranted on "The View" that Fox, which donated $5 million, should have coughed up even more. Rosie then blasted PRESIDENT BUSH for his "Idol" appearance to pump the charity show with wife LAURA when he’s spending taxpayer’s money on the war! Ellen, who personally ponied up $100,000, ripped Rosie for being way out of line. "Ellen is outraged," said an insider. "She’s extremely proud she was involved…and can’t believe Rosie would cast a dark cloud on something that’s doing so much good for kids."
