Kris Jenner - who manages her famous children's careers - doesn't sleep a lot so she's able to start work very early in order to do business deals around the globe.

The 62-year-old showbiz matriarch explained: "I get up really early every morning at about 4 or 5, I don't sleep a lot so I'm trying to get a lot done early morning. I plan everything, make sure everything is fine all the way [while] I'm on the treadmill, I drink lots of coffee to get me going. 

"I plan my day while Europe is up, get in most of my phone calls while New York is up and by the time L.A. wakes up I'm ready to go."

But the 'Keeping Up With the Kardashians' star knows the family empire wouldn't be so strong if her offspring weren't so passionate about what they do.

Speaking at Vogue's Forces of Fashion event in New York on Thursday (11.10.18), she said: "I think that what I've learned over the years is how to find that balance and [know] what each one of my kids is capable of. One thing that I couldn't have all the greatest ideas in the world if I didn't have kids with an amazing work ethic and creativity. 

"My job is affected by the fact that they're so engaged everyday. It's really great and so that makes the biggest difference at all."

And though Kris guides her kids with their businesses, she leaves the creative decisions to them.

She said: "With Kim [Kardashian West] and Kylie [Jenner] and the beauty brands, I'm really involved on the business side. 

"When they get into their creative mode with the contouring shades and what the next collection of Kylie's lip line is they really have absolute control.

"Anything I say will probably be overridden. [Kylie will] say 'Mom you don't understand green lipstick' and I'll be like 'No I don't.'

"I think that instinctually they've always landed on their feet so they know what they're doing and I try to stay out of that."
