IN A BRUTAL mother-daughter cage match, Kris Jenner threatened to slap daughter Kim Kardashian with a whopping $10 mil­lion lawsuit!

Sources say mom-ager Kris hit the roof when Kim, who’s expecting a baby girl with rapper beau Kanye West, im­plied she was on the verge of quitting the family’s E! Network show “Keeping Up With the Kardashians.”

“After hearing that Kim dissed the family empire in a magazine in­terview, Kris flipped out and called a summit at her office,” revealed a close source.

With Kim, her brother Rob and Kris’ hus­band Bruce Jenner at the meeting in late February, “Kris pointed a finger in Kim’s face and told her that if she quit the show, she’d sue the living daylights out of her,” the source added.

“Kris said she’d hit Kim up with a ‘management fine’ of $10 million and then prod E! into filing a lawsuit against her too.

“I’m not sure if Kris was just trying to scare Kim, but Kim was shaking and on the verge of tears, and for a minute it seemed as if Kris might actu­ally haul off and slap her.”

As the family’s manager, Kris takes a 10 percent cut of all her children’s earnings.

And while Kim is her favorite, Kris is furious that the 32-year-old mom-to-be might ruin the family brand, said the source.
