Kris Jenner's famous family may have had their reservations concerning Rob Kardashian's budding romance with Blac Chyna in the past, but ultimately, she just wants her son to be happy and healthy.

A source tells E! News that the reality family's matriarch is not focusing any negative energy on Rob's current relationship, and instead, "is just happy that Rob is taking care of himself and working out."

There's been a definite improvement in Rob's health over the last few months since he and Blac Chyna began dating. In addition to looking physically slimmer, Kardashian has seemed to build back his confidence and has been spotted out and about several times after spending the last few years out of the spotlight. 

Our source says Chyna's a great influence on Rob despite the ongoing speculation, telling us, "You see how great Rob looks ever since they got together, she's all good for him."

Whether it's being photographed more often in public, sharing pictures on social media or showing off his fitness "progress," Rob has made positive changes that have not gone unnoticed by his family.

"They haven't seen Rob come out of his shell like this in years," a source previously shared with E! News. "The family is very grateful for Blac's help with giving Rob ‘confidence' again and putting his health and fitness first."

The insider also added at the time, "Kris Jenner would like Blac Chyna to start coming to family events once things have calmed down a bit. All the sisters are happy to have their brother back. Kylie Jenner is also coming around now."

Kris shared a heartfelt post last week in honor of the Keeping Up With the Kardashian star's 29th birthday, sharing a throwback black-and-white photo of her son looking dapper in a tuxedo.

"Happy Birthday Rob!! God blessed me beyond measure the day you were born. You are the most amazing man who is kind, funny, smart and you have the best heart. You are beautiful inside and out and have brought so much joy into my life," she wrote. "Thank you for being the best son a Mom could ever dream of...I love you soooo much @robkardashian and I'm so proud of you. Mommy #blessed #love #happybirthdayrob."
