Domestic dynamo Rachael Ray's new show debuted Monday and a dust-up with icon Martha Stewart already has occurred.

Four staff members from Martha Stewart's show tried to sneak into a taping "The Rachael Ray Show" show last week, but a security guard who works for both shows recognized them and had them ejected, said Monday. Ray's show, taped in New York, began its nationally syndicated run, competing against Stewart's daytime show.

The four were asked to leave because they "lied about their names," said. A Stewart spokesman says they were asked to leave by one of Stewart's former audience coordinators now working for Ray and not by a guard.
