Donald Trump's ex-wife IVANA is convinced the billionaire developer's public falling out with ROSIE O'DONNELL is nothing more than a publicity stunt. O'Donnell upset Trump, the owner of the Miss USA pageant, last month (DEC06) when she ridiculed him on her magazine talk show The View for giving hard-partying beauty queen TARA CONNER a chance to redeem herself during a much-publicised press conference. And Trump hit back calling O'Donnell "a crude, arrogant, pushy, disgusting slob". But Ivana is quick to point out that both her ex and O'Donnell have benefited from the war of words. She says, "Donald and Rosie, they're getting fantastic ratings, they're getting publicity, they're really using it as a marketing tool, not because they are enemies, and I understand that only too well."
