Whoa! Kim Kardashian went completely ballistic after sister Khloe woke her up an hour early on Sunday's 'Kourtney and Kim Take New York.' But this isn't just a simple spat. Kim is positively livid over the intrusion.

Kim makes an angry phone call to her sister, then curses her out in a profanity-laced email. Wisely, Khloe points out that "something else" is going on with Kim, namely her troubled relationship with then-husband Kris Humphries. Which we wouldn't know anything about.

Watch the fireworks below.
