Kim Kardashian -- My Baby Shower Invite Is Better Than Yours

Just how over the top were Kim Kardashian's music-box baby shower invitations? Really, really, really over the top -- and TMZ has the first photo proof.

The invite to Kim K's June 2nd bash -- sent to a guest close to Kanye West -- arrived as a fully functional music box, complete with a spinning ballerina ... dancing to a lullaby version of Kanye's "Hey Mama."

Not only is the invite playing the baby daddy's tune, but the ballerina bears a striking resemblance to Kim herself -- just in case anyone forgets who this party is REALLY celebrating.

According to the invites, Kris Jenner, Shelli Azoff (wife of uber-manager Irving Azoff), Kourtney and Khloe Kardashian are hosting the party. Recommended attire ... garden chic. We think that's rich people speak for casual.

Now here's the "Hey Mama" lullaby -- listen and pretend like you were invited.
