As you probably know, Rob Kardashian has been going through a bit of a rough patch for the last 18 months or so.
Most of his family has been treating the troubled 28-year-old with kid gloves, but his most famous sister is a firm believer in tough love:
Yes, Kim Kardashian never really went easy on Rob, and lately, she's been reveling in poking a bit of fun at her little brother.
It all started when Kim told Rolling Stone that Rob drinks, smokes weed and plays video games all day.
She must've enjoyed the response that she got her for telling it like it is, because Kim hasn't let up since.
If you watch Keeping Up With the Kardashians online then you may have witnessed one of Kim's most brutal burns earlier this season when she described Rob's tattoo of ex-girlfriend Rita Ora as going from a Barbie doll to a Cabbage Doll after he gained 100 pounds.
Now, Radar Online is reporting that Rob is so angry about the comment that he's threatening to "sue the ass off" his famous big sister.
Yeesh, we know you're mad, Rob, but do you really need to seize her most valuable asset?!
“Rob was so enraged when she made the joke that he reached out to seek legal advice right away,” an insider tells Radar.
“He’s got a good case, too, with all the humiliation he’s suffered on social media since the episode aired...The family is begging him not to follow through with it, but Rob insists he’s not backing down.”
It's possible that he could get a jury to see things his way, but hopefully, Rob has the sense to not go through with this.
Not only is KUWTK still paying his bills, but he's dealt out his fair share of public humiliation, too.
We seem to recall a certain someone comparing his sister to "the b-tch from Gone Girl" on social media not all that long ago.
Family's tough Rob, but it only gets tougher when you burn your bridges.
