brightcove.createExperiences(); Kris Jenner is sticking by her son.

Despite the family drama his new romance with Blac Chyna has caused, Rob Kardashian and Jenner have continued to spend time together.

On Wednesday, Kardashian, 28, posted a photo on Instagram of his mother’s arm bling, which included two diamond-encrusted Cartier bracelets and a watch.

“Hey pretty mama,” he captioned the picture, adding several heart emojis.

Later in the evening, Jenner, 60, hit up Craig’s restaurant in Los Angeles for dinner, wearing the same jewelry.

Given Blac Chyna’s complicated history with the Kardashian-Jenners, the relationship has created some tension – particularly after Blac Chyna was arrested last week on public intoxication and drug charges, with police saying she was allegedly in possession of two ecstasy pills and acting “unpredictable” and “angry” at an airport in Austin, Texas.

“It’s troublesome that she was caught with drugs,” a source told PEOPLE of the family’s reaction. “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 family is glad that Kardashian seems to be getting back on track. A source previously told PEOPLE that while the family feels that it’s “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,” the source added.

And so far, Jenner appears to be standing by her son: last week, Kardashian and Blac Chyna were spotted driving to Jenner’s Calabasas, California, home, and on Monday the momager promoted her son’s sock line on Twitter and Instagram.
