Stars finally credit Blac Chyna for changing Rob's life

All credit to Blac Chyna for changing Rob Kardashians life for the better, and now, even the reluctant sisters, Kim and Khloe Kardashian are backing the relationship even though it puts them in an awkward position!

There's no denying that Rob's relationship with the model has not only made him drop some weight or come out of hiding and depression, but he's becoming a father for the first time.

In a new preview clip from "Keeping Up With The Kardashians", Kim and Khloe discuss the romance - eventually deciding that it must be a good thing.

"Don't we kind of think it's a miracle that Rob, who doesn't even show up to Christmas for the past three years, literally he wouldn't leave his room, but the fact that now he's created a Snapchat, the fact that now he wants to be so public, blows my mind," Khloe introduces the topic.

And Kim agrees and even mentions Rob's pregnant fiancee by name: "She gave him confidence, more power to her. After Rob and Blac Chyna started dating, Rob is now, like, all over social media and, like, out and about."

However, Chyna found the Kardashian family unwelcoming when she started dating Rob back in January. Although she was once Kim's BFF, she was ditched from the inner circle after her ex, Tyga dropped her and started dating Kylie Jenner nearly two years ago.

That romance is still ongoing - putting the other family members in an undeniably awkward position, not least because Tyga and Chyna share custody of their young son King Cairo.

In our latest report, Kylie has dumped Tyga for reasons not yet known. Sources say the couple ended their nearly two year relationship a few days to the 2016 Met Gala in New York on May 2.
