The Kardashian family drama over Rob’s new romance with model Blac Chyna doesn’t seem to have affected his relationship with his mom, as he posted a picture on Instagram as he hung out with Kris Jenner.

The 28 year old posted a picture on Wednesday night (February 3rd) of Kris’s arm jewellery, featuring a top-range watch and Cartier bracelets encrusted with diamonds. “Hey pretty mama” he captioned the photo, adding several heart emojis.

Later that evening, 60 year old Jenner was spotted dining out in Craig’s restaurant in L.A., sporting the same jewellery.

Of course, much has been made of Rob and Chyna dating, because of her history with Kylie Jenner’s current boyfriend, rapper Tyga. Chyna, whose real name is Angela Renee White and is also a good friend of Kim Kardashian, used to date the rapper and had a child with him, before they broke up amid rumours that it might be because of Jenner.

Last week, Chyna was arrested for public intoxication after appearing “angry” and “unpredictable” in an airport in Austin, Texas, with police reports suggesting that she was in possession of two ecstasy pills at the time.

“It's troublesome that she was caught with drugs,” a source told People of the family's reaction to last week’s arrest. “There is a concern now that Chyna might not be great for him. Nobody wants their relationship to have a negative effect on Rob or end badly.”

Nevertheless, the Kardashian family is said to be pleased that somebody has made Rob happy, even if it is somebody they regard as controversial. Another People article claimed the family found it “definitely very annoying that Chyna is the one that could get to him, at least Rob seems happier… …it’s difficult to not be at least a little bit excited that Rob finally seems to have snapped out of the funk.”
