It is hard to believe that her cost has gone up, but that's the fact. Paris Hilton becomes even more famous than ever since she was sentenced behind bars for violating her probation. Not only she dominates media headlines with her every move, but also there's a high-demand of her in the market. All wants Paris, and PETA is not an exception.

The People for the Ethical Treatment of Animals (PETA) wants the heiress to support their movement, asking her to make use her time behind bars to empathize with cooped up chickens.

PETA spokesman Dan Mathews revealed, "We're asking Paris to narrate our Kentucky Fried Cruelty video showing how chickens are routinely crammed into tiny cages and suffer broken wings and legs. Unlike inmates at the jail in L.A., these animals get no reprieve or medical treatment."

Also he said, "We have a good track record at reaching celebrities behind bars. When Martha Stewart was incarcerated we wrote to her and got a very friendly reply saying that she'd stopped wearing fur, and when she got sprung she narrated PETA's anti-fur video."

As of Paris, the planned slogan for her campaign video reportedly is "KFC - that's not hot."
