After all, he is mama's (only) boy! Rob Kardashian posted a photo of Kris Jenner via Instagram on Wednesday, February 3, amid the ongoing family drama surrounding his new relationship with Blac Chyna. 

Jenner's son, 28 -- who finally resurfaced this week in public -- shared a photo of his mother's hands clutching her sunglasses. "Hey pretty mama," Kardashian captioned the pic, tagging his mom and adding a series of heart-eyed emojis.

Jenner has been actively promoting Kardashian's sock line, Arthur George, via Twitter this week, along with his sisters' endeavors, including Kourtney and Khloe's new Architectural Digest cover and Khloe's FYI talk show, Kocktails With Khloe.

Hey pretty mama 😍😍😍 @krisjenner

Behind closed doors, however, there's drama. Rob's latest social media update may be surprising to some as the family remains opposed to his new relationship with Chyna, who was arrested last Friday, January 29, in Austin, Texas. 

As reported by Us Weekly, Chyna was booked for public intoxication and possession of a controlled substance, which later turned out to be ecstasy pills tucked away in her glasses case. Following the incident, Kardashian drove from L.A. to Austin — a 20-hour trek — to pick her up.

A source told Us Weekly this week that Rob and Blac Chyna initially "bonded over their pain" caused by other members of the Kardashian-Jenner brood. "Both of them felt f--ked over by the family," one source told Us.

Us also reported that the Kardashians and Jenners are having a hard time coming to terms with Rob's new romance. “They are shocked, confused and in disbelief,” a source close to the family told Us. “Kylie says Rob has stabbed her in the back."
