Kim Kardashian insists she did not have sext with another man. The newly engaged starlet (and onetime NFL enthusiast) is threatening legal action over this week’s In Touch cover story, which claims she sent “kinky” messages to New England Patriots player Bret Lockett behind the back of her NBA fiancé, Kris Humphries.

“I knew this was a game to her, and this is what she does,” the tab quotes Lockett as saying. “She pursued me.”

In a letter to In Touch obtained by TMZ, Kardashian’s attorney dismisses the “caught cheating” claims as “at a minimum, damaging, defamatory, and an invasion of her privacy.”
