The Hump made a big mistake in the way he tried to break off with his girlfriend Myla Sinanaj. He obviously didn’t learn anything from Tiger Woods.

Unfortunately for Kim Kardashian I don’t think she can say too much considering she is have a very public affair with Kayne West.

Kim Kardashian has just served Kris Humphries’ ex-girlfriend, Myla Sinanaj, with a subpoena in the divorce case … TMZ has learned.

As TMZ first reported, Myla was in a boyfriend/girlfriend relationship with Kris since mid-January — something Kris was desperately trying to hide … to the point his people lied about the relationship.

Sources say Kim’s lawyer wants to know if Kris said anything about his marriage which might relate to his claim Kim defrauded him — in other words, did he blow his cover during pillow talk. We’re told Kim’s lawyer also wants details about hundreds of texts and emails exchanged between Myla and Kris.

I wish these two would just get divorce already, so everyone can move on.
