The Kardashian-Lamar wedding is tomorrow and all the details are just starting to be organized a day before the wedding.

The reality TV star and basketball star will tie the knot at music manager Irving Azoff’s home in front of around 250 guests. A rehearsal dinner will take place tonight near the beach in Santa Monica.

As for the wedding entourage, both of Khloe’s sisters Kim and Kourtney are said to be maids of honor, while their little sisters Kylie and Kendall Jenner are among the bridesmaids, along with Khadijah Haqq, Malika Haqq and Lauren London. Lamar’s close friend and business partner, Jamie Sangouthai, will serve as one of Lamar’s best men, with the groomsmen’s role given to Robert Davis, Alex Harris, Lester Knispel, Jeff Schwartz and Khloe’s brother, Rob Jr.

While everything seems all set, there’s been news that both Khloe and Odom want a prenuptial agreement, but since they need to get married on Sunday, there isn’t enough time to lawyer-up the details of the agreement. Since the couple needs to tie the knot on Sunday because one of the Kardashian reality shows is footing the $1 million bill for the wedding, but the deal is that the wedding must be shot this Sunday. Their solution? The couple will be signing a postnup, so the paper they will be signing on their wedding day isn’t a marriage contract, but “an acknowledgment that it’s not really an official wedding, to prevent misunderstandings down the road.”
