Khloe Kardashian is not spilling the beans on the sex of her pregnant sister Kim Kardashian, but revealed on the TODAY show details about the baby shower invite.

When asked by the show hosts, Matt Lauer and Savannah Guthrie if Kim was having a boy or girl, Khloe responded:

"I will say this Sunday we are going to reveal it," she said. "We find out the sex of the baby on the show."

Khloe offered a tease to the luxury baby shower invite. Guthrie held up the white container, then opened it to reveal a music box with a spinning ballerina inside. Khloe said the lullaby playing was written by the baby's father, Kanye West.

Although Khloe didn't say if Kim was expecting a boy or girl, she did reveal the reason why ballerinas were chosen to be included.

"Kim loves ballerinas," Khloe said. "Kim doesn't like baseball."

Khloe also said that the ballerina wasn't a sign that she's having a girl, but that the invite was designed all white to serve as a neutral color.

"It's very natural," Khloe said. "Kim likes what she likes."

Khloe was on the show to promote the premiere of her family's hit-reality show, Keeping Up With The Kardashians.

"We really had no idea to that season one was going to be as big as it is, so to have eight is such a blessing. It is shocking that there's still so much to be said and now Brody and Brandon are on the show," she said. "You get to follow Kim in her pregnancy."

In the preview video below, Kourtney, Khloe and mom Kris Jenner all accompany Kim to the doctor's office to find out the sex of the baby.

"Look at that! Look at the little ankle! Oh Kim look!" Jenner is heard saying in the background. "Do you see a little pee-pee?"

The camera cuts away as soon as the doctor reveals the news of the gender, enticing fans.

Keeping Up With the Kardashians begins its eighth season this Sunday, June 2, on E!
