In Touch magazine is running a cover story that Kim Kardashian was caught cheating on her fiance Kris Humphries with NFL player Bret Lockett and Kim’s ass is in an uproar (so you can imagine) and she’s threatening to sue both the magazine and Lockett.

According to the article Lockett says:

“I knew this was a game to her, and this is what she does.”  Lockett adds, “She pursued me.”

Considering she has cameras up every orifice on a daily basis one would think this would be captured and probably put into an episode of the Kardashians. If it isn’t in Keeping up With the Kardashians my bet is that it’s false.

TMZ has received a copy of the letter Kim’s lawyers have sent to In Touch, part of which says:

“are, at a minimum, damaging, defamatory, and an invasion of her privacy.”

The cover of the magazine claims a 5-month affair. This is going to get ugly.
