If Kim Kardashian was annoyed at Kanye West for partying without her, she is going to be seriously angry when she hears that a Canadian model is claiming to have slept with him.

Leyla Ghobadi is claiming that she and Kanye had a fling, while Kim was pregnant, after meeting last summer at a gig in Atlantic City.

Leyla (right) is claiming Kanye has been cheating on Kim during her pregnancy.

Apparently the rapper spotted her in the crowd and invited her backstage. The pair they had cocktails before he allegedly invited her back to his hotel room. She declined.

The following evening Leyla and her friends were invited to another gig, this time in Montreal. Again she was invited to Kanye’s hotel room. This time she said yes.

“We began to make out for a while – and next thing I knew, we were both naked and having sex,” she told Star magazine before saying that Kanye described his relationship with Kim as “for publicity and nothing serious.”

Kim and Kanye announced their baby news last last year.

Leyla said that she met up with Kanye again in October (she claims she didn't know Kim was pregnant at this time) and was even contacted by him last weekend. She refused to meet him last weekend saying: “I would never do that to someone.”

Speaking about her reason for the revelation she said: “This is going to destroy the Kardashian family. It’s bad. It’s really bad. It’s just embarrassing. But if I were Kim and about to have a baby, I would want to know.”
