HOLLYWOOD - The Desperate Housewives cast members are keeping a watchful eye on everybody on the set of their hit TV show, in an effort to find out who's been leaking gossip about them to the press. Teri Hatcher, Marcia Cross, Eva Longoria, Felicity Huffman and Nicollette Sheridan have been plagued by numerous rumors--including denied reports of cat fighting--ever since their show took the ratings by storm. And they've now embarked on a mission to catch the person responsible for the relentless gossip. Sheridan tells Maxim magazine, "The press doesn't want to hear that we all get along, that we're enjoying the work and one another. They love to build you up and then tear you down. People love all the drama that's created."There seems to be some sort of mole on the set. Somehow things seem to get out... We've been trying to find him."
