Kim Kardashian Officially Reveals She's Having a...

Kim Kardashian is having a girl!

OK! News: Guess Kim Kardashian's due date! Our guess is this day in June...

She revealed the news in tonight's season premiere of Keeping Up with the Kardashians. In the episode, Kim went to the doctor along with her mom, Kourtney, and Khloe for the unveiling, and it was totally sweet to watch the sisters find out together (Where was Kanye, though? Hmmm).

OK! News: You've gotta see this adorable Throwback Thursday of a baby Kim!

Kim's baby being a girl didn't come as a huge surprise, however. When her baby shower invites came out a few weeks ago, they featured a music box with a ballerina inside. Time to start imagining female K names!

Are you surprised that Kim's having a girl? Who do you think the baby will look like? Do you think she'll have a K name? Tell us in the comments below or tweet us @OKMagazine.
