Rob Kardashian has had no contact from sister Kim since her wedding and is ignoring the efforts of his other sibling Khloe Kardshian.
Rob Kardashian hasn't spoken to his sisters Kim and Khloe for a month.
The 27-year-old sock designer has not been contacted by Kim since he failed to attend her wedding to Kanye West last month, and has shunned attempts from his other sibling to repair their rift.
A source told RadarOnline.com: ''[Rob] has no reason to talk to Kim. They haven't been on good terms for a very long time.
''Kim hasn't bothered to even attempt to talk to him since returning from her honeymoon, [while] Khloé has sent him text messages and left him several voice mails.
''Rob hasn't returned any of Khloé's phone calls or texts. He feels completely estranged from his sisters and family. He really isn't in a good place.''
Rob did fly out to Paris, France, for Kim's nuptials, but after getting into an argument with her - in which she mocked his recent weight gain - he flew back to Los Angeles instead of travelling to Florence, Italy, for the ceremony and insiders have admitted there had been tension between the pair for some time.
A source said previously: ''Kim and Rob haven't been speaking to each other for months -- she thinks he is lazy, and bringing down the family name because of his physical appearance.
''After arriving in Paris, Rob and Kim got into a very heated argument because she thought he was just moping around the hotel.
''She encouraged him to go out and sight see, which he declined to do.''
