Nicole Scherzinger works out to stay awake

Nicole Scherzinger combats a sleepless night by working out on a treadmill.

The American songstress has a demanding work schedule, juggling her solo music career with her role as a judge on the US version of The X Factor.

Nicole has revealed her unusual way of dealing with sleep deprivation due to her gruelling routine.

"I've had to get off a flight with no sleep and go straight to work. In those situations, I get on a treadmill for ten minutes and do intervals where you walk for a minute, then sprint as fast as you can, then walk, then jog," she revealed in the January issue of UK magazine Glamour.

Nicole has a positive working relationship with her fellow X Factor judges, Simon Cowell, Paula Abdul and LA Reid.

The stunning star says each one brings something different to the table.

"Simon encourages all the judges to be real. Paula is even better in person. And LA Reid is a force to be reckoned with," she gushed.

Nicole is preparing for the release of her debut studio album Killer Love.

The singer has promised to always dedicate time to her music career.

"Absolutely," she said, when asked if more albums are in the pipeline. "Music is my driving force."
