Blac Chyna is being credited by the Kardashian clan for Rob Kardashian’s current positive disposition. Kris Jenner is especially “grateful to Chyna for rehabilitating her son,” reports claim.

Kris, 66, the clan’s matriarch, has come to appreciate Blac Chyna for giving her son new direction in life  but admits she does not know her that much.

“I haven’t really seen her that much and I don’t know her as well as everyone else but she seems like a really nice girl and I just haven’t been around her too much,” Kris said of Chyna during an interview on the Kyle and Jackie O Show on Australian radio station KIIS-FM 1065. “But you know, he’s been very, very happy lately and I think he’s in a really good place. I don’t know too much about their relationship.”

Rob Kardashian, who began dating Blac Chyna in January this year, has gotten slimmer and healthier these past few months. Kris and the rest of the family are thankful to Chyna for helping him overcome his health issues and reconnect with the family. Last week, the 29-year-old reality star, who ditched many of their family gatherings, celebrated his birthday with the whole clan. However, Chyna was apparently absent at the birthday bash.

It appears Chyna has played a vital role in boosting Kardashian’s self-esteem. The once-reclusive Kardashian member is now working on a few projects and is appearing in public more recently, said Kris.

Even sister Kendall Jenner is happy that her older brother is hanging out with them again. “It’s all really amazing and we’re just very happy to kind of see him and kind of hang out with us again,” Kendall told E! at the Estée Edit by Estée Lauder event.
