The pregnant reality star announced she was having a daughter on Sunday night's episode of 'Keeping Up With The Kardashians'.
Kim Kardashian and Kanye West
The couple have managed to keep the sex of the baby under wraps up until now - even going so far as to buy all white baby clothes so people wouldn't guess.
But as she let the cat out of the bag, Kim said: "I'm so excited to be having a girl. Who doesn’t want a girl?
"I know that's really what Kanye has always wanted. He wanted a little girl.
"What kind of child will I have? A very tutu-y, like, princess?"
Kim and Kanye are due to welcome their first child together in the summer.
