Khloé Kardashian has always had a strong relationship with younger brother Rob Kardashian, so it's no surprise that the reality star opened up during an event at the 1OAK nightclub in Las Vegas on Friday about Rob's ongoing struggle to lose weight and why he remains out of the public eye 

Gossip Cop reports that her sock designer brother has made headlines for his recent struggle with weight gain, opting out of appearing on the family's hit reality series "Keeping Up With the Kardashians" in order to focus on his health. However, according to sister Khloé, Rob has continued to struggle with constant scrutiny surrounding his absence from the public eye.

"I just feel, especially over the last year, Rob has become very introverted and has a kind of social anxiety," Kardashian revealed to Wonderwall.
