The youngest of the Kardashian sisters also gave the TODAY hosts a baby shower invitation on behalf of Kim, and while the invite had a music box with a ballerina figurine inside of it, Khloe said not to read too much into it.

"Kim loves ballerinas … she likes what she likes," Khloe said of her sister, who's expecting her first child with boyfriend Kanye West.
