KIM KARDASHIAN has declared war on her man­ager mom KRIS JENNER over the family’s whop­ping new $40 million reality TV deal!

“Gimme Kimmie” is telling friends her business mogul mom cheated her out of millions, insiders say, and now she’s demanding a bigger chunk of cash than the rest of her camera-hogging clan.

The curvaceous diva, 31, is so angry that she’s even threatened to walk off the family’s hit E! show “Keeping Up With the Kardashi­ans,” sources say.

“Kim screamed at her mom, ‘You are using me!’” a source close to the series told The ENQUIRER.

“She yelled, ‘You are robbing me of millions! You’d be NOTHING with­out me!’

“Kim is behaving like an out-of-control diva. She’s demanding more than her fair share of money and insisting that since she’s the star, she deserves it. But her mom isn’t buying into her greedy, self-serving demands.”

Kris, 56, negotiated the new re­cord-setting $40 million deal for three more seasons of the hit show, which launches its seventh go-round on May 20.

According to the terms of the deal, Kim would split the big bucks from the hit show equally with her sisters Kourtney, 33, and Khloe, 27, her mom, and Kris’ husband Bruce Jenner. Kris and Bruce’s teenage daughters Kendall and Kylie and brother Rob get a smaller cut.

But when mama Kris cut the deal, she didn’t tell Kim that the main story line in the show would focus on her still unsettled divorce from NBA player Kris Humphries and her current romance with hip-hop star Kanye West.

“Kim was fine with being wo­ven into the clan’s spinoff shows ‘Khloe & Lamar’ and ‘Kourtney & Kim Take New York,’ and being featured in a number of episodes of the main show,” said another source.

“But she doesn’t want her love life to be center stage all the time. She feels the TV spotlight helped ruin her re­lationship with Kris, and she doesn’t want to wreck what she has with Kanye.

“Nobody loves money more than Kim, but she’s ready to take the whole show down if she doesn’t get what she wants. Now that she’ll be the focus for the next three seasons, she wants to make more money than anyone else. She told Kris, ‘Make it right, or I’m outta here!’”

Meanwhile, Kim and Kris put a good face on their contentious feud when they attended the White House Correspondents’ dinner in Washington together April 28, but sources say that behind the scenes the two are butting heads.

“Simply put, Kim feels that her mother and the show’s producers are conspiring against her to put most of the weight of the show on her shoulders while giving equal shares of the money pot to every­one else in the family,” divulged the source.

“She told her mother that she felt like she was being taken for a fool. But Kris was quick to defend herself. She told Kim, ‘You are our reigning star and I set this all up for you. At some point soon, you’ll get your own spinoff show and you’ll get all the money.’

“But Kim isn’t buying it. She wants a lion’s share of the money pie NOW.”
