Kim's Turning Into A 'Psycho' From Her Extreme Diet & Fitness Addiction!

Insiders exclusively revealed to RadarOnline.com that Kim Kardashian's drastically slimmer physique is distracting from the fact she's becoming a "psycho" hot mess behind the scenes — and her diet and fitness "addiction" are taking a major toll on her personal life!

"She's gone from being body bore to an all-out robot, with nothing else in her life except working out or fixating over her food," dished a source of the 35-year-old reality star.

As a result, noted the source, "Her hormones are totally out of whack and she's grumpy, over-demanding and tough beyond belief of the people around her."

"Everyone — from Kanye to her closest friends — has noticed a major change in the way she's barking orders and refusing to listen," blasted the source.

"It's no wonder Kanye's burying his head in work — Kim's a bitch on wheels to be around right now!"
