The intimate event took place at Scarpetta, a restaurant inside the Montage Beverly Hills hotel, and lasted about three hours.
So, who exactly was in attendance?
"It was just some family and friends," a source who was there tells E! News. "Nothing crazy!"
In fact, the whole celebration, which went off without a hitch, was very low-key.
"It was fast," the source adds. "There were a couple of speeches from Kris Jenner, Kris Humphries' dad and her sisters."
And it certainly seems like everyone enjoyed themselves.
"Had such an amazing night with my family and friends," Khloé Kardashian Odom tweeted later in the evening, as did the bride-to-be herself.
"What a fun night with family & friends!" wrote Kim.
She also revealed that while she did have "a freak-out moment" about a week ago, it was simply about wedding preparations and nothing to do with Kris, saying that their relationship is "just so normal, healthy, trusting and easy."
When the subject of her late father, Robert Kardashian, came up, Kim said he will most certainly be there in spirit, and she plans to carry something of his down the aisle.
"When you lose someone that's so close to you, these are the moments that you wish your dad can be here," she said. "You will feel the heart in this whole ceremony, and the whole reception, and the whole atmosphere. I think you'll feel the presence of my dad. You will feel that love in the room, and that's going to be the best part of this whole night."
