Out of all of the Kardashian-Jenners, 28-year-old Rob is the most private.
The reality star slowly backed his way out of the family’s Keeping Up With The Kardashians reality show before quitting the TV world entirely, removing himself from the public eye and becoming a recluse.
Despite not appearing on the show, Rob’s wellbeing is a regular topic of conversation between his mum, Kris Jenner, and older sisters, with the star moving in with Khloe as the family discussed getting him a therapist.
Although things seemed to be on the up for Rob, he was noticeably missing from the Kardashian-Jenner’s family Thanksgiving card, even though everybody from Kris’ new boyfriend, Corey Gamble, and Kourtney’s ex, Scott Disick, made the shot.
Kris later insisted that Rob had been with them for the occasion but left to visit friends before the photograph was taken.
However, Kourtney and Khloe have recently sparked fresh concern among fans after they seperately took to their social media pages to share touching messages to their little brother.
Yesterday Khlo shared a throwback photo of Rob tenderly kissing her on the forehead, captioning the pic: “If only you could see yourself through my eyes!
"I’ll forever be obsessed with you! My one and only! #MyAce [sic]”
And earlier today Kourtney followed her sister’s lead, sharing a throwback of herself with her brother simply writing: “Bobby” followed by the heart emoji.
Kris, Kim, Kendall, and Kylie are yet to post about Rob, but two members of the family referencing him in such a short space of time has left fans concerned.
Whatever’s going on, at least Rob can depend on his huge family to be by his side.
