Nicollette Sheridan has revealed that the Desperate Housewives cast are determined to expose an on-set 'mole'.

The actress, who plays Edie Britt on the hit US series, has decided that she wants to find out who has been selling stories about cast members to tabloids - including constant reports of alleged feuds and arguments.

Sheridan told 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."
