Kris Jenner has reportedly told her son Rob Kardashian that he needs to go to fat camp. According to Star Magazine (via the Daily Mail), Jenner thinks he's an embarrassment to the family and is pressuring him to lose weight.

There's been reports claiming that Kardashian has been struggling with his weight ever since he split from British singer Rita Ora in 2012.

"Rob is fatter than ever, and Kris finally flat out told him he's an embarrassment to the family," a source told Star. "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 report also claims that his sisters - Kim Kardashian, Khloe Kardashian and Kourtney Kardashian - are also urging him to drop a few pounds.  

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

None of the Kardashians have responded to Star's allegations. It's not clear how true their story is but Khloe has also been criticized for her weight. According to the magazine, Jenner is very adamant that her son goes to the camp to work out his issues.  

"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," the source said.

According to the Daily Mail, on a recent episode of "Keeping Up With the Kardashians," Kardashian spoke about his weight struggles.

"I've been the most unhappiest person for about a year and a half and it's very, very easy to fall off the wagon," he said. "I need to literally dedicate my entire life to my fitness.
