In reaction to his embarrassing Oprah appearance the article states:
Mr. Cruise's spokeswoman, his sister Lee Anne De Vette, said she had not heard anything negative after the "Oprah" appearance. "You're looking at someone who's genuinely very happy," she said. "The response we've gotten back is complete enthusiasm and exhilaration for his enthusiasm and exhilaration. He's a very happy person."
First of all, he has the potential to damage his career, lose roles and industry respect for his insane Scientology ramblings and teenager behavior. No good publicist would allow a client this type of career-damaging freedom.
On that note, I would NEVER hire my sister as my publicist. Your publicist should be someone who has never seen you naked, is entitled to money in your will or who is only a publicist riding on your own famous coattails.
