Kim Kardashian will file for divorce this morning, after 72 days of not-so-wedded bliss to Kris Humphries ... TMZ has learned.
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.
As we first reported, the couple has a prenuptial agreement ... Kim made sure of that.
Rumors of a split had been swirling for some time and the two were spotted out to dinner earlier this week ... looking less than pleased with one another.
Kim Kardashian will never, ever move to Minnesota ... everyone knows that ... except Kris Humphries.
Sources close to the former couple tell TMZ ... one of the main points of contention in the marriage was where the couple would live after all of the wedding madness finally died down.
We're told Kris was passionate about eventually settling down in Minnesota, where he's from ... and believed Kim was on board with the plan. She wasn't.
Sources tell us Kim -- who's from L.A. -- wants to stay near her family ... and she also feels that staying in town is the best thing for her career.
So why didn't this conversation come up before the $10 million wedding? We're told the two talked about their future ... but got caught up in the hooplah and figured they would simply figure it out after they tied the knot.
Sources say it's not a nasty break-up ... but we're told the two have come to a realization that it's not a long-term fit.
Kris Humphries desperately tried to save his marriage to Kim Kardashian, because he's telling friends ... he doesn't believe in divorce.
Kris, who's a religious guy, is telling friends he and Kim discussed the possibility of divorce, but he believed they could work their problems out.
We're told Kris didn't know Kim was actually filing legal papers until this morning.
And, Kris is telling friends ... the stories that he was cheating on Kim are B.S.
We're told Kris is "bummed."
"After careful consideration, I have decided to end my marriage," she said. "I hope everyone understands this was not an easy decision. I had hoped this marriage was forever, but sometimes things don't work out as planned. We remain friends and wish each other the best."
Kris Humphries is willing to do whatever it takes to repair his broken marriage -- telling TMZ, "I'm committed to this marriage and everything this covenant represents."
Kris adds, "I love my wife and am devastated to learn she filed for divorce ... I'm willing to do whatever it takes to make it work."
