Teaching English to Entertainment Industry Professionals

0I am an English teacher in Poland. My humble school just got a very special student - a singer with an international celebrity status. She demands fast and very specific results - better oral communication with business people, journalists, and fans. I want to help her but she is my first student with such specific needs. For example, I have unsuccessfully tried finding any books teaching English to the entertainment industry professionals. Any ideas will be appreciated.02br
