Kim And Kris Have Their First Fight!

The honeymoon's over before it even began!

After arriving home from their 3-hour wedding rehearsal at the Montage Hotel in Beverly Hills, Kris Humphries and Kim Kardashian got into their first spat after the groom-to-be threw one of her bags at the cameras. The 30-year-old reality star wasn't pleased with his behavior and she definitely let him know it!

The rehearsal dinner at The Montage's Scarpetta restaurant was packed with close to 80 people ... mostly members of the Kardashian family. Khloe was the first to give Kim a toast, while Kris Jenner told Kris that he "better be nice to Kim," according to Us.

The twosome are set to tie the knot tomorrow in a lavish Montecito ceremony reportedly costing $20 million. Kim and Kris are said to be postponing their honeymoon until next summer so that she can get back to New York and resume filming her reality show. While in NYC, the newlyweds will enjoy an encore wedding celebration hosted by wedding planner Colin Cowie and media CEO Jason Binn.

So can Kris handle every bit of his life captured by the cameras? Marrying Kim is pretty much going to guarantee him zero privacy, and with this recent outburst ... could be trouble.
