Rob Kardashian Ignores Kim Kardashian, Khloe Kardashian After Ditching Wedding: Rob's Weight Gain Causing Family Problems

"Keeping up with the Kardashian" reality star, Robert Kardashian is allegedly ignoring his sisters, Khloe Kardashian, and Kim Kardashian after he decided to skip the 33-year-old's wedding to Kanye West in May.

According to RadarOnline, the reality star has been distant towards his sisters ever since going through his weight problems.

 "[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," one source revealed, "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."

The 27-year-old returned to the states after ditching Kim's and Kanye's European wedding and has allegedly kept to himself, barricading himself from family and friends.

 "[He] has been holed up in his house, and hasn't been returning calls from concerned family members," the source added, "Rob made the decision months ago that he didn't want to have a recurring storyline on the upcoming season of Keeping Up With The Kardashians, and drastically cut back on filming."

June 10, Khloe posted a childhood photo on Instagram of her and Rob to grasp his attention. In the caption Khloe wrote: "I miss my best friend @robkardashian."
