One Direction have revealed how they always eat sweets before going on stage as it helps them to calm down.

The chart-topping boyband, who this week debuted their Pepsi commercial, admitted their backstage rituals in an interview with Company magazine.

Harry said, "Sometimes I feel sick before I go onstage. I like our pre-show pep talk as it helps to calm me down," before Niall added, "I eat Haribo before hitting the stage. That helps.”

Zayn, who this week claimed he was a ‘bad boy,' then went on to discuss the worst thing about going on tour:

"I guess the hardest part of being on tour is being away from home so much and missing our friends and family.

"But then again, I get to travel all over the world with four of my closest friends, so we keep ourselves positive and the fans help us a lot!"
