And besides their adorable selves, much of the credit goes to host with the most Khloé Kardashian Odom. Not only is Khloé planning Kim's big bachelorette blowout in Vegas this weekend, but she also threw her sister and her fiancé an engagement party at her L.A. home last month.
Despite having only three days to put the shindig together, she managed to make it a total success.
"We decided on a Monday that we were going to have it, and then it took place that Thursday," she wrote on her blog about the bash.
So who made the list for this last-minute soiree?
Of course, all of the usual suspects were there, including her famous family and BFFs Lala Vasquez and Brittny Gastineau. Lamar Odom's Lakers teammate and the guy who introduced Kim and Kris, Jordan Farmar, also attended.
The future Mrs. Humphries went for a bridal-inspired look, wearing a white zip-up tank dress, while Kris chose a black button-up shirt for the party.
Just because he's walking down the aisle doesn't mean the New Jersey Nets player is cutting back on his diet. He and Lamar dug into the spread, which included sliders and chicken satay, while Kim opted to indulge in some cotton candy.
And while everyone looked fabulous for the occasion, it seemed like a relatively tame affair for the Kardashian clan.
We're betting they'll get a lot wilder this weekend in Vegas!
