After not attending Kim Kardashian's wedding to Kanye West in May, Rob Kardashian is reportedly no longer speaking to sisters Kim and Khloe Kardashian.

According to Radar Online, a source says Rob “has no reason to talk to Kim” and the siblings “haven’t been on good terms for a very long time.”

Rob Kardashian flew back to L.A. before his sister’s wedding to West in Italy. The decision was reportedly made at the last minute just a few hours before the ceremony began. He reportedly left following a major fight with Kim. During the argument, a source claimed Kim brought up Rob’s weight and his lack of engagement during the family's time in Paris before the wedding.

“After arriving in Paris, Rob and Kim got into a very heated argument because she thought he was just moping around the hotel,” the source said. “She encouraged him to go out and sightsee, which he declined to do.”

Another source added that nothing has been resolved between the pair since their return from the trip. He isn’t speaking to Kim and he's also ceased communication with his sister Khloe.

Kim “hasn’t bothered to even attempt to talk to him since returning from her honeymoon, [while] Khloe has sent him text messages and left him several voice mails,” the source told Radar. “Rob hasn’t returned any of Khloe’s phone calls or texts. He feels completely estranged from his sisters and family. He really isn’t in a good place.”

Rob wiped his entire Twitter account once he returned to L.A. from Paris but has returned to social media in June. He even sent a birthday wish to his sister Kourtney Kardashian’s boyfriend, Scott Disick, on Twitter. 

Khloe Kardashian recently posted an image on Instagram of herself and Rob as kids. She captioned it with, “I miss my best friend,” hinting at a possible rift between the pair.
