Katy Perry bans staff from looking at her

Katy Perry has allegedly banned her staff from talking to or looking at her.
The 'E.T.' singer has apparently issued a 23-point list of demands for her current 'California Dreams' world tour.
The Daily Star claims that chauffeurs have been told they must not start a conversation with Perry and warned "not to stare" at her through their rear-view mirror.
Requesting autographs or pictures is forbidden and the drivers should not open doors or touch her luggage, the reports adds.
Other demands on the star's rider include her dressing room being draped in cream or soft pink and containing two cream-coloured egg chairs and floor lamps in "French ornate style".
An insider told the paper: "Few people knew Katy was like this. She seems such a nice girl."
Perry, currently in Japan for four dates, also demands her dressing room contains "strictly no carnations" but asks for "white and purple hydrangeas, pink and white roses and peonies". 
It was recently reported that Perry had fallen out with her mother, who has written a book about her daughter.
