Khloe Kardashian would fire her mother Kris Jenner from her role as her manager if they weren't related - because she's constantly criticising her weight.

The curvy beauty has been vocal about her body image insecurities in the past, and admits her confidence takes a hit when Jenner nags about her figure.

And Kardashian insists she wouldn't hesitate to end their working relationship if they weren't family.

She tells Cosmopolitan magazine, "Listen, my mom believes in us more than we believe in ourselves. But she is also our manager and trying to protect our brand.

"She'll say, 'Oh, you're a little too fat right now.' If she were just my manager, I'd have fired her right then. You can't talk to me like that."
