Kim Kardashian and Kris Humphries celebrating her 31st birthday at Marquee nightclub in Las Vegas (10/22)

While I'm sure we'll never hear the real reason Kim Kardashian is divorcing Kris Humphries just 72 days into their marriage (i.e. he's dumber than a box of rocks and is in constant danger of meandering into the street and being hit by a taxi), here come the excuses. TMZ says Kim and Kris are splitting up because he wanted to move to Minnesota and she wanted to stay in Beverly Hills. And no, I don't know why I went all fairy taley with that headline.

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.

If only Kim and Kris had known about this potential Minnesota/Beverly Hills conflict before getting married. If only there was something -- anything -- that could have prevented this . . . a "conversation"-type thing between them if you will.
