Report: Kanye West Cheated On Pregnant Kim Kardashian With Canadian Model, She Claims

A gorgeous 24-year-old model from Canada tells this week's Star that Kanye West cheated on Kim Kardashian with her, and that the Heartless singer admitted he's only with the reality star to help his career.

Leyla Ghobadi tells Star her revelations are "going to destroy the Kardashian family … but if I were Kim and about to have a baby, I would want to know.

“It’s bad -- it’s really bad -- it’s just embarrassing."

Ghobadi, a Montreal native, told the magazine she first met the cocky Paranoid singer in New Jersey when he spotted her in the crowd during a July 2012 show at Revel’s Ovation Hall in Atlantic City -- a show Kim also attended. Ghobadi said Kanye deputized a roadie to bring her backstage, where he invited her out for cocktails.

West “invited me back to his hotel room, but I refused, as I felt it was too rushed," Ghobadi told the magazine.

Ghobadi said West gave her free tickets to the next night's show and backstage passes -- again he, asked her back to his hotel room in hopes of hooking up -- but Ghobadi said she demurred, as she was "concerned that he was seeing Kim Kardashian."

West “told me that his relationship with Kim was for publicity and nothing serious,” Ghobadi told Star, admitting she finally relented to the superstar's charms, accompanying him to his hotel room.

“We began to make out for a while and next thing I knew, we were both naked and having sex,” she told Star, adding that a second meeting in October -- while Kim was already pregnant with his child -- took place in New York, while Kim was in South Florida.

Ghobadi told Star she's refused Kanye's further advances with Kim's pregnancy obvious at this point, adding, “I would never do that to someone."

Reps for Kardashian and West have denied Star's report.
