(Cover) - EN Showbiz - Kris Jenner was reportedly "visibly shaken" when her daughters Kim and Khlo Kardashian were no shows at a celebration party.

The Kardashian clan has recently signed a three-year $40 million contract extension with E! network to produce more TV reality shows.

Kris, who has acted as manager for her family and negotiated original deals, hosted a party to celebrate the feat in New York City in late April.

Kris' daughter Kourtney was the only child in attendance at the affair and the matriarch was reportedly incensed at Kim and Khlo's absence.

"Kourtney was there with her boyfriend, Scott, but Khlo left abruptly before the festivities started and Kim skipped it altogether even though she was in New York," an eyewitness told In Touch magazine.

"[Kris was] visibly shaken and in tears. She pulled Kourtney over and started a fight with her about how she was raising her little son, Mason. Kourtney was telling her to mind her own business. She said Khlo was right about how controlling Kris is."

Apparently her daughters may no longer be interested in having Kris act as their manager. Kim is thought to be renegotiating a spokesperson contract with Tao nightclub in Las Vegas without the assistance of her mother.

"She's selling herself to the highest bidder, with a starting price of $150,000 per appearance," the insider revealed. "She stands to make a million dollars, but she's cutting Kris out, even though Kris negotiated her first contract with Tao. It's interesting." (C) Cover Media
