Talking trash is part of Hollywood, isn't it?
The rules of celebrity fight club are simple: 1. You must always talk about your fight. 2. You must ALWAYS talk about your fight. 3. If someone yells "stop," goes limp, or taps out, they will forfeit any current reality TV deals. Isn't that how Kim Kardashian got her ass to surpass Paris Hilton?
For as long as there's been the notion of celebrities, there have been celebrities with beef, and pitting one star against another in the manner of Edward Norton vs. Edward Norton is what drives the show business machine. Who needs ESPN when you have Us Weekly? Now go grab your popcorn with one hand and "Go Team Drizzy Drake" banner with the other and flip through (ok, so maybe you need three hands) for the most trash talking celebrity feuds.
