Kourtney Kardashian thinks former NFL star Keyshawn Johnson pulled a fast one on her.

The reality star, 35, believes that the Los Angeles-area home she bought from the former football player, 42, is mold-infested, reports TMZ.

According to the website, the mold, which was covered by a coat of paint, was discovered by the eldest Kardashian sister’s decorator while installing fixtures around the house.

Kardashian, who is expecting her third child, feels that it’s too dangerous for her young family to stay in the house and has checked everyone into the Montage hotel in Beverly Hills.

She’s also said to be considering legal action.

But  Johnson is said to be furious at the allegations coming from the Kardashian camp, according to a source close to the ESPN commentator.

Johnson claims to have never painted a wall in the house during the two-and-a-half years he lived there.

That same source said that Johnson believes that the mold developed after the sale of the house when a bathroom pipe sprung a leak, and that he would never have knowingly exposed his own children, who were living in the house, to mold.

A Kardashian family representative did not return a request for comment.
