Anyone watching this could tell you that it was bound to happen.
Blac Chyna and Amber Rose were as thick as thieves after Chyna's ex and baby daddy, Tyga started dating Kim Kardashian's sister, Kylie Jenner.
Oh, and Kim allegedly came between Rose and Kanye West, according to Rose.
Got all that?
Well, now that Chyna has been welcomed into the family fold (she and fiance Rob Kardashian are expecting their first baby together), it appears that she has no time for Rose.
"Honestly, Amber kind of feels like Blac Chyna turned on her," a source told Radar Online.
"It is almost impossible for Amber to be around Blac nowadays because she is always around the Kardashians and Blac knows how much Amber cannot stomach the family."
The family member who has been the most compassionate and kindest to Chyna is Kim.
"Blac Chyna is getting close with Kim now and Amber just does not want any part of it. Amber cannot stand any of them really and none of them can stand her," the source added.
Kim shared a Snapchat this week of herself rubbing Chyna's belly at a family party, and Kim was reportedly the one who helped the family come around to Rob and Chyna's relationship.
"It seems like Blac Chyna has made her choice and it is driving them apart more and more each day."
Without knowing too much about Chyna and Rose's relationship, it sounds like it was born out of a mutual hatred for the Kardashians.
Unfortunately, when one friend takes up with a member of the family (however estranged he might be from them), there's always a slight chance that they could reconcile.
This is probably what happened with Chyna and Rob.
However, Rose did make a great point recently while doing press for her VH1 talk show, The Amber Rose Show.
"You can’t help who you fall in love with, and in this case it was Rob," Rose told the Daily Beast.
"It fit perfect with her. They’re great for each other."
