This isn’t the first troubling behavior from the reality star. The 28-year-old’s spiraling life has been documented on “Keeping Up with the Kardashians,” going back three years.
"The attitude has always been that when Rob gets his act together, starts working out and loses weight, everything will be good and he will be happy," says a production source on the family's reality show to PEOPLE. "But behind the weight gain is this very unhealthy mental state that he keeps struggling with.”
Rob has also faced scrutiny about his burgeoning weight, which was reportedly the reason he didn’t attend Kim's Italian wedding to Kanye West last May.
