Rob Kardashian is said to be furious with his older sister, Kim. She recently sat down with Rolling Stone to discuss her brother, among other things. In the article, Kim claims that all Rob does all day is smoke weed and hang out with his friends.

"He has gained weight. He feels uncomfortable being on the show, and that's OK,' Kim told Rolling Stone. "Do I think he smokes weed, drinks beer, hangs out and plays video games with his friends all day long? Yes."

"Rob and Kim had been cool again and were getting along. Now he's furious at her again for her comments to Rolling Stone," a source told Us Weekly. "He was been bitching her out on her phone. He's mad - p****d as hell ..." The source continues, "Rob has blocked Kim on his phone. He doesn't want to hear what she has to say. He says there's no excuse she could possibly have for saying that. He will not forgive her."

During the interview, Kim was asked about Rob, who barely ever appears on "Keeping Up With the Kardashains." Rob has gained weight and is said to be fighting depression, according to Yahoo News.

"It's not Kim's personality to nurture," another source explained to Us Weekly of the tough-love star. "She loves him, but she's direct."
