It looked like they were getting along well during their last Twitter exchange when Kim joked about the funny voice notes that Rob sends her.
A few days later, Kim's Rolling Stone interview was released and when she was asked about her reclusive brother, she replied, "It's not that mysterious, what's happening with Rob. He has gained weight. He feels uncomfortable being on the show, and that's OK."
Totally fine, but what she said next was kind of a bummer for her little bro. "Do I think he smokes weed, drinks beer, hangs out and plays video games with his friends all day long? Yes," she concluded.
Apparently, Rob is furious about that and some other comments Kim made to the mag about him. "Rob and Kim had been cool again and were getting along," a source exclusively told Us Weekly. "Now he's furious at her again for her comments to Rolling Stone. He was been bitching her out on her phone. He's mad - pissed as hell."
Hopefully they'll be able to hash it out behind closed doors and this little sibling spat won't play out on social media like the last one did.
