Kim Kardashian couldn’t stop gushing about her Italian wedding to Kanye West on “Jimmy Kimmel Live” Monday. “It was the most amazing experience," the reality-TV star said. But unfortunately for fans of the newlyweds, one tabloid is now alleging that their marriage is nothing more than a business arrangement.

“Their marriage is a sham. It was from the start,” an unnamed family "insider" told InTouch Weekly. Inside the tabloid’s Aug. 18 cover feature “Kim’s Charade Exposed,” the source goes on to claim that Kardashian, 33, was never in love with her 37-year-old rapper beau and consistently “bashes” him behind his back.

“She used to trash-talk Kanye, saying he smelled bad. She once confessed she’s disgusted by him,” said one insider, who claims that in recent months the “Keeping Up with the Kardashians” star has dissed the musician over everything from his lack of desire for sex (with her) to his continuous stream of public rants.

“She talks about how ridiculous, inarticulate and egotistical he sounds when he goes on these rants in interviews,” said a source. “She moans to her sisters about how he comes off like a total idiot.”

So why stay married? Despite already having two failed marriages under her belt, one to music producer Damon Thomas and most recently, NBA player Kris Humphries in 2010, insiders say Kardashian doesn’t fear public scrutiny of her marriage’s demise as much as losing her true love: money.

“Both Kim and Kanye are profiting from being together,” reported the magazine, an insider adding of Kardashian, “Every decision that she makes in life is calculated. With Kim it always comes down to the bottom line. Why should her marriage be any different? It’s all a business arrangement.”

Last week, a source close to the Kardashian camp addressed reports of marital strife, telling People magazine that their relationship, despite rumors of an impending split, is not in jeopardy. “They wish they could be together all the time,” a source told the magazine. “They see each other a lot more than people realize, they just don’t feel the need to publicize it every time.”

InTouch Weekly’s report follows a similar view of Beyoncé and Jay Z’s marriage recently shared by fellow musician Akon. In an interview with TMZ, the “Smack That" performer called the A-listers' union “corporate” following weeks of reports that the duo are headed for divorce.

“Their relationship has been more a business to the outside world than an actual relationship,” he said. “Now, to them it may be a relationship, but it was presented to the world and it feels more corporate.”
