Rob Kardashian Going All Out Against His Family This 2015? Kim Reveals Reasons For Brother's Weight Gain

Rob Kardashian is allegedly on the warpath against his family this 2015, as Kim Kardashian touched on her brother's weight gain in an interview with Matt Lauer.

According to tabloid Celebrity Dirty Laundry, Rob Kardashian will allegedly spill a family secret this 2015 involving the biological father of Khloe Kardashian.

"Despite the fact that Alex and Khloe are basically twins, the Kardashian Family has continuously denied the claims, until now that is," it claimed. "Rob Kardashian is a hot head, his overall hate for his family combined with his alleged depression and drug abuse has made the ex-reality TV star a loose cannon."

Meanwhile, Kim Kardashian weighed in on Rob Kardashian's weight gain in an interview with Matt Lauer which will be aired on Monday's "Today" show.

She said, "I think he's just going through a phase where he's not comfortable in his own skin, and he is working really hard to get back to where he really wants to be."

When Matt Lauer suggested that Rob Kardashian's weight gain struggles are aggravated by fame and notoriety surrounding the family, Kim Kardashian replied, "I don't necessarily think it's because of the fame."

"I think it's been circumstances in his life that he just really hasn't dealt with," she explained. "Whether it's, you know, the loss of our father, or certain breakups, or, you know, he was extremely close to Lamar [Odom] and when, you know, Khloé and him broke up, that was really hard on him. So I think it was a couple things."

It was earlier alleged that Rob Kardashian is going to sue the family this 2015 because his weight gain is still being used as a storyline for "KUWTK."

According to the latest issue from OK! Magazine, Rob Kardashian is reportedly planning to sue his family for $50 million.
