A French-Canadian model has come forward to claim that Kanye West cheated on girlfriend Kim Kardashian with her on at least two occasions — once while Kim K was already pregnant.

Speaking exclusively with Star magazine, 24-year-old Leyla Ghobadi, a waitress-slash-model-slash-marketing-director from Montreal, says she and Kanye first hooked up last July, after he invited her to his hotel room after an Atlantic City show.

According to Ghobadi, Kanye spotted her in the crowd at Revel’s Ovation Hall and asked a member of his crew to invite her backstage, despite Kim being mere yards away in the VIP box.

Star says it has seen footage from that night that supposedly backs up Ghobadi's claim by showing West conversing with a stagehand about her.

Ghobadi insists she refused Kanye's initial advances, but he persisted, asking her to come back the following night for his second show.

Kanye once again invited Ghobadi backstage. This time, however, she went all the way.

"He told me . . . he wanted to ‘hook up,’ but I was concerned that he was seeing Kim Kardashian," Ghobadi told Star. "He told me that [the relationship] was for publicity and nothing serious."

Next thing Ghobadi knew, "we were both naked and having sex."

In October, Ghobadi says she and Kanye met in New York and got it on again, this time with the now-pregnant Kim K back in Miami.

She says Kanye tried to put the moves on her as recently as last weekend, but this time she turned him down cold, having since learned that Kim was with child.

"I would never do that to someone," Ghobadi said.

Asked why she was coming forward with this now, Ghobadi told the publication that if she were Kim "and about to have a baby, I would want to know."

She added: "This is going to destroy the Kardashian family. It’s bad. It’s really bad. It’s just embarrassing."

A rep for the Kardashian Klan has flatly denied Ghobadi's allegation. Kanye's camp, meanwhile, has yet to respond.

UPDATE: TMZ says a Kanye spox told them the self-proclaimed god never cheated on Kim, and Ghobadi's claims are a "blatant attempt by a misguided individual who is clearly seeking publicity, and another in a series of malicious stories drummed up by non-credible 'news' sources."
