Katie has fired her old security team because they were way too close to Tom Cruise. The bodyguard and driver worked for Tom for years, before Tom even met Katie. So obviously they will be loyal to Tom. It was when he and Katie hooked up, that he assigned the duo to Katie full time. TMZ reports that Katie appeared with a new security detail made up of 5 to 6 bodyguards. Sources say Katie let the old team go after filing for divorce last week.
