Kanye West denies cheating, seen in new 'Cold' video for Vogue

Kanye West claims he never cheated on Kim Kardashian with a Canadian model/bartender.

TMZ reports that the woman is accusing him of being unfaithful may be only doing it for her 15 minutes of fame.

24-year-old Leyla Ghobadi recently did an interview claiming she met Kanye at one of his concerts in July 2012 -- three months after Kim and Kanye began dating. She says Kanye had his security invite her to have drinks after.

She claims they later engaged in two sexual encounters while Kim was pregnant -- and that Kanye claimed his relationship with the Calabasas retailer turned amateur porn star turned TV reality star was a fabricated "sham" in order to increase his fan base.

But a rep for Kanye tells TMZ it is all lies.

"This most recent attack on Kanye West and his family is totally without merit. It's 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."

The rep tells TMZ, "This is a sad attempt to hurt two people trying to live their lives."

Today Vogue.com released Kanye West's Yeezus. It was at this year's Met Gala, where he debuted both "Black Skinhead" and "New Slaves," which he would also perform at SNL and Governors Ball in the weeks to come. In anticipation of the new album, out June 18, Vogue as an exclusive video of West's performance of "Cold" at the Party of the Year.
