Warning: TMZ Causes Cancer

Sure, we dish it out, and we can take it too -- but Illeana Douglas definitely crossed a line when she walked around Hollywood last night with a sign reading, "TMZ causes cancer. Stop filming celebrities, start filming poverty."

The irony -- or we're hoping, the point of this gutless stunt -- is that Douglas was at the premiere of and supporting the new season of "Dirt," the FX series starring Courteney Cox, which is all about filming celebrities.
