In light of a story in this week’s In Touch magazine alleging that Kim Kardashian carried on a five-month affair with Brett Lockett while she was dating her new fiancé Kris Humphries, Kardashian has issued not just a strong denial but a letter to Lockett threatening to slap him with a lawsuit if he does not retract his allegations of a fling and cease making any more false allegations about their supposed affair. The reality television star also took to her blog to deny the alleged affair saying she has never met, spoken to, texted, called or even heard of Lockett. Lockett however insists that he had a fling with Kardashian and has all the evidence needed to prove his story. A representative for the magazine told CNN the tabloid stands by its story.
