Rob Kardashian is upset with his elder sister Kim Kardashian.
"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. Do I think he smokes weed, drinks beer, hangs out and plays video games with his friends all day long? Yes," Kim told the publication.
Rob is very much disturbed by her comments and has vowed he would never forgive her.
"Rob and Kim had been cool again and were getting along," a source said. "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."
"Rob has blocked Kim on his phone," the insider added. "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."
Reports that the siblings are not on good terms started circulating after Rob did not attend Kim and West's wedding in Florence, Italy, last year on 24 May, after she reportedly commented about his weight gain. He has withdrawn largely from public life of late and also unfollowed half his family on Twitter.
In March, the sock designer compared the 34-year-old Keeping Up With The Kardashians star to a sociopath character from the psychological thriller movie Gone Girl.
He had shared a disturbing image of Rosamund Pike's character in the film, Amy Dunne, covered in blood.
"This is my sister kim , the b***h from Gone Girl,,," he captioned the image.
