The former 'American Idol' judge is currently building a huge new mansion in San Fernando but those working on the home have reportedly been warned they must not interact with the 43-year-old star, reported Contactmusic.
"She has made it clear that if any of the contractors, drivers or domestic help made eye contact or speak to her she will not be impressed.
"This is despite the fact this is a long-term project so some of the workers will be on site for up to a year," a source said.
