These days, it has become more and more popular to garner some free publicity by slamming Paris Hilton. After all, she is the one that gets the most publicity, apparently for nothing, so no one would ever come to her defense.

The last celebrity to attack Paris on the record is Tina Fey, a former star and writer for 'Saturday Night Live'. Fey said that, for the brief period of time that Hilton spent on the set of the show as co-host, she proved that she is the most despicable piece of white trash that ever walked the earth, so self-centered that no one else fits into her little world.

During a radio interview with Howard Stern, Tina said that, never in her life, had she felt so powerless to act as she did when she was with Paris, a spoiled brat that would listen to no reason and that would do only what she really wanted to.

Fey recounts the many times Paris did not agree with what the writers had put in the script, saying that she wouldn't do 'that' (without any explanation) and then fleeing to lock herself in her dressing room. And, as if that weren't enough, Paris never came up with any new ideas for the show, save that of playing all the girls she hates: 'I want to play Jessica Simpson, I hate her. You should do a show about Jessica Simpson because she's fat', the heiress kept telling Fey.

'She's a piece of s**t. The people at SNL were like maybe she'll be fun, maybe she won't take herself so seriously. She takes herself so seriously! She's unbelievably dumb and so proud of how dumb she is. She looks like a tranny up close', Tina said in the interview.
