Rob Kardashian: My Mom Is A Monster! Kris Jenner Says The Overweight Reality Star Is 'An Obese Person With A Failed Sock Line,' Claims Report

Mommy issues?

While Rob Kardashian has tried to stay out of the spotlight given his hefty new physique, sources close to the overweight reality star claim it's his mother, Kris Jenner, who is the source of his pain.

"Everyone thinks he skipped the wedding because of Kim, but it's him mom who makes him feel terrible," a source told Star magazine.

"Rob is spiraling out of control and it's all his mother's fault. The world thinks the Kardashians are so happy, but Kris treats Rob like dirt. He says she's a monster."

As RadarOnline.com previously reported, Kim harshly told her brother while in Paris for her nuptials to Kanye West that Rob "is lazy, and bringing down the family name because of his physical appearance."

Jenner is said to have echoed Kim, claims Star Magazine.

"Kris says he's the only one of her kids who is an embarrassment — an obese person with a failed sock line," the source charged.

"Rob needs to stop lying and own up to the fact that he has issues. Until he admits to his problems, he's not going to get better."
