On the season premiere of Kourtney & Khloe Take Miami this Sunday, the sisters get into a nasty bitch fight during a naked photo shoot.
And this isn't just regular drama, this is Kardashian drama!
Kourt gets upset at Khloe for being hung over from the night before and before you know it, the claws come out!
"You f***ing hung over bitch, can't you act professional and get this done for five minutes?" snaps Kourtney. To which Khloe fire back: "I forgot, you're such a mom - you're SO perfect now! You've never been drunk. You used to be the party queen of life, so shut the f*** up, you hypocrite."
