The 24-year-old model told a tabloid that her affair with West began in July 2012, and continued even after Kim announced she was pregnant.
“This is going to destroy the Kardashian family,” the model told Star. “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.”
West’s rep denied these “malicious stories” in a statement to People: “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. This is a sad attempt to hurt two people trying to live their lives.”
Kim’s rep also denied the allegation.
Kim and Kanye’s daughter will come into the world in July. The couple recently celebrated the baby shower in Beverly Hills.
