Khloé Kardashian Tells Blac Chyna to Back Off Kylie Jenner (REPORT)

Blac Chyna has fired MORE shots at Kylie Jenner — and now Khloé Kardashian is stepping in!

Shortly after the former stripper made fun of the teen's lips on Instagram, the 25-year-old decided to share a racy bedroom photo [see below] with the caption "Urgently" — allegedly mocking Kylie's overuse of the word "permanently."

“Khloé called Blac Chyna yesterday and let her have it after she saw that,” a source told ‘Radar Online,’ adding, “because Khloé is pretty much Kylie’s mother, she is not going to let this bimbo go and talk smack about her baby sister.”

However, “She [Blac] knows too much on that family through her friendship with Amber Rose and they all feel she will use it against them if any of the Kardashian girls seriously try to do anything stupid to humiliate her.”

This was probably around the same time the model shared screenshots of private text conversations she allegedly had with Tyga, 25, who is the father of their two-year-old son, King Cairo.

No word on how Kylie feels about that, but according to the source, the 17-year-old “Cannot wait until she is 18 so her and Tyga can make out on her Instagram and Blac can just sit home and cry about it.”
