RadarOnline.com has learned that Khloe Kardashian has gone to war with Blac Chyna over the jailbird's budding romance with her brother Rob — and the women recently went at it during an "ear-splitting explosive" phone call!
Khloe, 31, "feels so betrayed by Rob, because he's told her to back off since moving in with Blac," a family insider told Radar exclusively.
"She doesn't like this relationship one bit, knowing just how much he wears his heart on his sleeve."
As Radar reported, Blac, 27, and 28-year-old Rob have been flaunting their new relationship, including in front of the cameras.
"Blac's a trouble-making gold-digger and Khloe doesn't want her near Rob," said the insider. "The last phone call she had with him, Blac snatched the phone away and gave Khloe a piece of her mind."
"Blac thinks Khloe and the family bully Rob, and now he's even more in love with her than before because she stuck up for him."
