Rob Kardashian has been steadily gaining weight since last year, and now, mom Kris Jenner is allegedly saying it is time for fat camp. In November, Kardashian told E! that he was working out twice a day to lose the weight, but it is unclear if he has been keeping up with that commitment. He was recently spotted out, wearing a hoodie and sweatpants, and it seems he has a double chin these days.

“Getting healthy ... is huge for me. I've really just kind of changed my whole lifestyle with taking supplements and working out twice a day. I really needed a change. There's just a lot going on in my family, a lot of stress and negative attention,” he said back in November.

He is right. His sister, Khloe, whom he lived with until recently, is going through a divorce from NBA star Lamar Odom, after he  admitted to cheating on her and using illicit drugs early last year. There have also been numerous rumors that his stepfather Bruce Jenner is having surgery to become a woman, and separated from Jenner after 22 years of marriage.

Kardashian has been on a mission to lose weight after getting chubby once his relationship with singer Rita Ora went south.

Now, it seems Kris Jenner has had enough. "She called him a fat slob and said he's losing out on business opportunities because no one wants someone as huge as him representing their products. She's told him that if he wants to continue to be an active part of their family, he's going to attend a camp and lose the weight once and for all," a source told Star magazine.
