Kim Kardashian and Kanye West revealed the gender of their unborn baby over the weekend at Kim's baby shower.

The couple revealed that they are expecting a baby girl. However, the public didn't find out that the couple was having a baby girl until the premiere of 'Keeping Up With The Kardashians' last night. During the show Kim had an ultrasound that revealed the baby's girls gender.

But really, Kim sent out invitations to her baby shower that were in the form of a ballerina music box. So, it was kind of easy to figure it out from that alone.
