Khloe Kardashian Blasts Rob for Acting ''Crazy'' & Disappearing on Blac Chyna

On this Sunday's episode of Keeping Up With the Kardashians, Khloe Kardashian puts Rob on blast after he goes MIA and disappears on his pregnant fiancée Blac Chyna for five days.

During a conversation with her sisters Kim Kardashian and Kourtney Kardashian, Khloe explains that they can't act like what Rob's doing "isn't wrong."

"If this was any man that we were with we would be pissed," Khloe says. "He hasn't spoken to her in days."

"Why?" Kourtney asks.

"I don't give a f--k!" Khloe replies. "You still need to check on her."

Khloe continues, "I don't care if it's our brother, facts are facts, it's crazy how he's acting. That's so f--ked up!"
