Stick a fork in ‘em! The KARDASHIANS are DONE, say top industry insiders.

It’s hard to believe that it’s been nearly six years since “Keeping Up With The Kardashians” preemed launching celeb-u-tards Kim, Khloe & Kourtney and the rest of endless family into national consciousness.

BUT after years of media over-exposure, it seems the world is finally had ENOUGH!

With the Kardashian brand tanking, ratings down and woozy Lamar Odom threatening to derail the entire family with his serial philandering and drug use, industry insiders agree that when the K-Klan’s contract is up in 2015, that’ll be IT!

With contract negotiations approaching, “maintaining their brand image is paramount [right now],” branding and marketing expert Liz Goodgold told RadarOnline as Lamar’s off-camera antics definitely don’t fit with the family’s on-screen narrative.

 “The family quickly closes ranks and silences negative information,” she explains. If Lamar were to break that omertà by exposing their secrets, Goodgold says, the show would likely not be renewed, because the “scope and scale of how they manipulate the media (would be) unveiled.”

Jennifer Pozner, the author of Reality Bites Back: The Troubling Truth About Guilty Pleasure TV agrees, “It’s been proven over and over that they’re masters of business and masters of manipulation. The expectation that anything that we see on TV about their relationships would be real is only the result of the fact that we don’t teach media literacy in this country.”

Pozner told Radar, “People are starting to say, ‘I think we’re over it.’” But because reality shows are very cheap to produce, she says, “E! is probably going to hold on as long as they can despite what the viewers want.”

What viewers want is to change the channel – for good.
