Despite Kardashian's pregnancy scare last week, the family of her estranged husband Kris Humphries is showing the reality star no mercy, calling the couple's marriage a "sham."

In an interview with U.K.'s The Sun, Humphries' aunt Dedria and uncle Mike talked about the basketball star's relationship with the reality television star.

"It was a sham," Dedria said. "My understanding of marriage is people are going to give it more than 72 days unless there's serious abuse. If I felt somebody had duped me and used me in front of the whole world, I would be very angry."

Humphries' uncle Mike, 60, revealed Humphries is being adamant in the divorce battle because he wants revenge. The basketball player wants "a pound of flesh back. I believe he wants payback," he told the newspaper, adding that Kardashian's mom Kris Jenner is pushing her family to fame and that she's "the mastermind" behind the family's riches. 

Dedria and Mike were among the 36 Humphries family members who traveled across the U.S. to attend the athlete's wedding to Kardashian in Santa Barbara, Calif., which the couple followed with a lavish honeymoon in Italy.

Dedria and Mike, who live in Michigan, said they do not own a television and barely knew who Kardashian was when Humphries announced his engagement to her. Dedria revealed that she even had to ask her hairdresser who the reality starlet was.

"She is impeccably groomed but it is a facade," she said. 

Dedria and Mike warned Kardashian's baby daddy and current boyfriend, Kanye West, to break up with her as soon as he can. Mike said, "He's a chump getting mixed up with her." 

Sources said West has been under a lot of heat by Jenner since Kardashian's pregnancy scare. A friend of the family said Jenner is upset at West for choosing his career over his girlfriend and unborn child by deciding to stay in Paris when Kardashian was rushed to the hospital in Los Angeles.

"Kris is livid with Kanye for not flying out to LA to be with Kim. She thinks he should have been on the next flight out to support Kim and that he is putting his career above her," the source said.
