Kim Kardashian and Kanye West's marriage is a sham, a new book has claimed. Ian Halperin's book titled Kardashian Dynasty also claims that the rapper would not have married Kim if he was not smitten by The Keeping Up With The Kardashian star's mother Kris Jenner.

"He [Kanye West] was smitten with Kris Jenner," the source explained in the book, according to RadarOnline. "In fact, I don't think he would have married Kim if Kris Jenner wasn't on the scene." "[Kanye West] found Kris smart, loving, and business-savvy," the source said. "He was enamored."

The couple have also faced divorce rumours in recent times, with some reports saying they have been living separate lives. The two currently are on a family holiday, while keeping fans updated on their experiences via social media.

The couple's marriage began falling apart after less than two years, an alleged source told RadarOnline.

"[Kim Kardashian] and Kanye [West] don't sleep in the same bedroom in the new house. At Kris's [Jenner] house they had to be together because there wasn't a lot of room. At the new house they have tons and tons of space and so they are apart even when they're home, and night is the worst time," the source said.

"[Kim Kardashian] and Kanye don't want to address the problems, so they act like they're happy in public, but they're not even sleeping in the same bedroom at home. They aren't happy," the source said.

"Kim is dealing with the kids at night and Kanye is working a lot...Kim and Kanye might live in the same house, but they don't even see each other sometimes," the source added.

Kim tied the knot with Kanye in May 2014. They have a daughter named North West and a son called Saint West.
