It's no secret that Rob could really use a shoulder to lean on while he deals with his personal issues. On a recent episode of 'Keeping Up With the Kardashians,' Kris Jenner admitted on camera that her son has gained more than 100 pounds in the past year.
"If I don't help him do something drastic, he's going to die," she said while fighting back tears. "I'm just waiting for this horrible thing to happen and there's nothing we can do about it."
