I must say, there are a lot of celebrities that act like total douche bags to people. I'm friends with a woman on Facebook who has been an extra in so many movies. She has more than 100 uncredited or background parts in many well known films.
She said Sylvester Stallone called her a 'B' word when they were filming the ending to
Cobra. She can be seen as a reporter for a second, and he was rude to her because she was asked to step aside. It's a shame that people get treated like that by the stars, but celebs are just people too. Fame has a dark side we rarely see.
After joining Facebook and Twitter, I no longer care about some singers anymore. Some of what they post is offensive.
