Rob Kardashian Mad at Kim Over Her Public Comments on His Weight & Drug Use

Kim Kardashian and her brother Rob have an on-again off-again type of feud. Right now they're in the middle of another battle round after Kim made fun of him in her big Rolling Stone interview. According to a source close to the Kardashian family, Rob is "furious" at Kim for saying he'd be skinny if he actually took meth.

"Rob and Kim had been cool again and were getting along," a source told Us Weekly. "Now he's furious at her again for her comments to Rolling Stone. He was been b*tching her out on her phone. He's mad — pissed as hell."

During the interview, Kim was asked about her brother Rob's absence. According to her, he hasn't been on the show because he is uncomfortable about his weight gain.

"It's not that mysterious, what's happening with Rob," Kardashian said of her brother. "He has gained weight. He feels uncomfortable being on the show, and that's OK. Do I think he smokes weed, drinks beer, hangs out and plays video games with his friends all day long? Yes."

It was at this point that the interviewer asked if there were deeper vices in Rob's life.

"It's not more like hookers and meth at the Ritz," she said. "No no. Or he'd be skinny."

The brother and sister got into a similar argument back in March. Apparently Rob felt that Kim was being two-faced about his struggles. At one point, Rob compared her to Rosamund Pike's character in Gone Girl on Instagram.

The Rolling Stone article is just another chapter in their sibling rivalry. Do you think they'll work it out?
