Amber Rose Hints Rob's Sisters Are Cool with Blac Chyna & Rob Dating

Amber Rose came to the defense of her BFF Blac Chyna and insinuated Rob Kardashian's sisters are no longer pissed about the relationship.

Amber arrived at LAX Thursday night fresh off supporting Wiz Khalifa's album release in NYC, and couldn't stop singing Rob and BC's praises.

Check out the clip ... she stops short of speaking for the Kardashians (wise move), but Amber definitely makes it sound like she got some intel during her meeting with Kim earlier this week.

The plot thickens, as they say.
