Rob Kardashian's 2015 weight gain has reportedly become worst, rendering the former "Keeping Up With The Kardashians" star at his heaviest weight ever.
According to several websites, Rob Kardashian's recent weight gain is the reason why he never showed up on Kris Jenner's 60th birthday party -- to dodge media criticisms and potentially, criticisms from his big sister, Kim Kardashian.
Rob Kardashian's relationship with Kim Kardashian started to crumble when Kanye West's wife publicly criticized him for gaining over 75lbs. over the past few years.
"It's not that mysterious, what's happening with Rob," Kim Kardashian told Rolling Stone in July. "He has gained weight. He feels uncomfortable being on the show, and that's OK."
"Do I think he smokes weed, drinks beer, hangs out and plays video games with his friends all day long? Yes," she added.
Kim Kardashian's statement about Rob Kardashian reportedly made the "KUWTK" star furious - a fury that apparently hasn't died down in time for Kris Jenner's "Great Gatsby"-themed birthday party.
Meanwhile, the events in Rob Kardashian's life all throughout the year 2015 seem to have taken a toll on him and his weight loss journey - among them is the health issues his father figure, Lamar Odom, is now facing.
On top of that, Rob Kardashian had reportedly had a fight with Khloe Kardashian after Lamar Odom's hospitalization.
"(Rob Kardashian) hates how (Khloe's) strung Lamar along and believes that's why he went even further off the rails than he would have had she just set him free," an insider for Radar Online reported. "She led him to believe there was a chance of a reunion for so long that he put everyone on hold and had to sit there while she was wined and dined by all these other guys."
With all the tension, pressure and emotions building up, Rob Kardashian's 75lbs weight gain from early 2015 have reportedly reached up to 100lbs.
"As a mom, it breaks my heart to see Rob going through what he's going through," Kris admitted in a "KUWTK" episode. "If I don't help him do something drastic, he's going to die. I'm just waiting for this horrible thing to happen and there's nothing we can do about it."
