Last week, Rob Kardashian was hospitalized and diagnosed with diabetes.
It was the latest in a long line of setbacks for the former reality star, whose self-destructive tendencies have done immeasurable damage to his health, his career - and his relationship with his most famous sister.
Yes, Radar Online is reporting that the feud between Rob and Kim Kardashian is still going strong.
In fact, sources say relations between the siblings are worse than ever as a result of Rob refusing rehab, despite his family and friends urging him to seek treatment.
The latest problem, it seems, stems from comments Kim made on the latest episode of Keeping Up With the Kardashians
Apparently, Rob is pissed about a scene in which Kim joked about a Rob's tattoo tribute to ex-girlfriend Rita Ora that's apparently been grown along with Rob's waistline:
"He covered it with a life-sized Barbie doll of Rita that has now turned into a Cabbage Patch Doll," Kim laughed.
"After Rob saw the episode, he told Kourtney and Khloe that he is done with her," a source tells Radar. "He is really trying to rid his life of all of the bad influences and sources of negativity and he thinks that the biggest one is Kim."
The feud dates back to when Rob compared Kim to the villain from Gone Girl in a shockingly snarky Instagram post back in April of last year.
In the months that followed, Kim made several snide remarks about Rob's lifestyle during interviews.
Insiders say Kim's remark on the latest KUWTK was the final straw.
"Rob really was trying to repair their relationship," one source tells Radar. "But she continually puts him down and she was the only one of his sisters that did not reach out to him when he was hospitalized.
"He is just done playing the nice guy and he told Kourtney and Khloe that he wants nothing to do with Kim from this point on."
