WATCH: Kardashian Sister Feud! Khloe Kardashian Calls Kylie Jenner a 'Little Bi***'

You would think your family would be the first to know about your birthday. But that wasn’t the case for Kylie Jenner!

The reality TV star forgot to invite her own sisters Khloe and Kourtney Kardashian to her 18th birthday bash!

When Kourtney informed Khloe about the party she replied, “What a little bi*** Kylie is” and called her up for some explaining.

Kylie claimed she was going to wait to tell them until it was set in stone but the sisters weren’t having it. “Don’t you want us to hold the date? What if we are busy?” they asked.

Kylie replied, “You’re never going to be busy on my birthday.” Feisty remark for the little Jenner!
