Kim Kardashian hasn’t announced her due date yet, but she is already preparing for it with a big baby shower.

E! News has learned that the invitations have been sent to a selected group of friends and family. The festivities will go down on June 2 to celebrate the arrival of KimYe’s baby.

Judging from Kanye’s recent display of unconventional methods, these invitations were a lot different than normal. As E! News details:

“They arrived at their intended destinations in music boxes that, when opened, played Kanye's tune, "Hey Mama," the tribute track he wrote for his own mother, as a wind-up ballerina twirled.”

With such an innovative invitation, you can bet that this baby bash will be one to remember.
