In addition, Kardashian and West's eight-month-old daughter North "Nori" West will reportedly be involved in the ceremony.
"North will have a large role in the wedding!" a source told Us.
Another source told the magazine there will be "lots of events leading up to the big day" for their guests.
However, "Kim isn't totally pumped about a huge wedding," an insider explained of the twice divorced reality TV star, "but she's going along with it."
Kardashian, 33, previously revealed West, 36, is very actively helping to plan their upcoming nuptials although it's typical for a groom to be uninterested in the process. She also announced they intend to get married in Paris.
"I think [Paris is it]. It's like our second home. We spend so much time there; We have an apartment there. So, we really love it," Kardashian said during a recent appearance on Jimmy Kimmel Live, reluctant to share any specific details of their big day.
"I'm not telling you where or the date, but I think it's kind of obvious that it's Paris."
A Kardashian friend also told Us, "She'll do one dress change."
