Kim Kardashian will file for divorce this morning, after 72 days of not-so-wedded bliss to Kris Humphries.

We're told even though the marriage was short, she will not seek an annulment. It's a garden variety divorce, in which Kim cites "irreconcilable differences."

We're told the date of separation is listed as today, Oct. 31, 2011.

Kim has hired disso-queen Laura Wasser, who has repped the likes of Britney Spears, Maria Shriver, Angelina Jolie, Ryan Reynolds, and Robyn Gibson, Mel's almost ex-wife.
