Reports are circulating that momager Kris Jenner has had enough of Rob Kardashian's weight issues and she's being pretty harsh about it.

Rob Kardashian Considers Weight Loss Clinic?

A source recently told Star magazine, "Rob is fatter than ever, and Kris finally flat out told him he's an embarassment to the family. 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."

The insider also revealed that Jenner has gone as far as demanding her son to go to fat camp to lose weight.

"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."

If he does decide to go to camp, it won't be the first time. Kardashian previously checked into a fat camp but it didn't seem to help.

"When he came back, he didn't look very different from when he left and Kris was not happy," the source added.

They went on to claim that Kardashian's famous sisters agree with Jenner when it comes to Rob shedding a few pounds.

"They're embarrassed to be photographed with him and bully him for being fat. They also tease him by leaving cakes and cookies around to tempt him."

It isn't clear how true this is, considering his big sister Khloe seems to be his biggest advocate when it comes to getting healthy and losing weight. Back in November she shared a picture of a gym on Instagram that implied she and Rob had been working out.

She included the caption, "No excuses!!!!! [Rob] and I went hard today."
