In photos taken earlier this month, and shared by the UK's Daily Mail, Rob looked nearly unrecognizable as he made a late-night stop at a Los Angeles In 'N Out. After exiting his white Range Rover SUV, the reality star was spotted in a black t-shirt and matching shorts.

During a recent episode of Keeping Up With The Kardashians, Rob's mother, Kris Jenner, expressed her concern for her son.

'If I don't help him do something drastic, he's going to die," Jenner told Kim. "I'm just waiting for this horrible thing to happen and there's nothing we can do about it."

Keeping Up With The Kardashians season 10 airs Sundays at 9 p.m. on the E! Network.
