Family sticks together through thick and thin.
While there's no shortage of in-fighting between the Kardashians, especially when it comes to Rob, they are taking this philosophy to heart ...
... by welcoming Blac Chyna into the fold.
It's a slow process, to be sure. But Kris Jenner praising Blac publicly for helping Rob Kardashian get his act together was no accident.
Jenner's overture was an olive branch of sorts from the Momager, who - along with Rob's sisters - infamously clashed with the stripper.
"They're all about loyalty," says a source.
That, and they recognize that over the last several years, Rob has lived a reclusive life and battled depression. Until Blac came along.
"Nobody's been able to help him," says the insider. "Khloé [Kardashian] and Kendall [Jenner] have really tried to get him out of the house."
"They could never do it."
Chyna could. And has.
Ever since Rob starting dating Tyga's baby mama - and drove to Texas to bail her out of jail - he's lost weight and shed more than pounds.
The younger brother of Kim, Kourtney and Khloe has stepped out at public events with his girlfriend and shared many a public picture.
Says the insider:
"She's come along and obviously it's made a huge difference ... Even [Kris] is actually super stoked on them being together now."
Despite Blac's bizarre history with Kylie and the family (below), "she feels like Rob was pulled out of his depression because of her."
And if Chyna continues to have that kind of impact on Rob, "They're really going to accept her into the family," adds the source.
Will Blac appear on Keeping Up? Will the Kards be bridesmaids in her bridal party when she marries Rob and they live happily ever after?
Maybe it's a little premature to go that far, but this is trending in such a very positive, inclusive direction. Who would've guessed?
