VIDEO : Khloe Kardashian Is Furious With Rob & Chyna: 'So Desperate And Fake'

Khloe Kardashian is known for speaking her mind and she doesn't hold back, even when it comes to family. Lately, the Kardashian sisters are upset with brother Rob Kardashian after he got engaged to Blac Chyna and announced it on social media without telling his family first. In a family as close as the Kardashians, who have been known to spy on their siblings dates before, that's a huge no-no. In a recent episode of Keeping Up With The Kardashians Khloe warns her sisters, "No one should congratulate them, that's so desperate and fake of whoever does first because I know someone's gonna break."
