Boyband One Direction are fast becoming the new pin-ups for teenage girls across the nation.
As the fresh-faced fivesome take the X Factor finals by storm, putting in show-stopping performances week upon week, we've noticed they've been wearing the Power Balance silicon wrist band – dubbed "the latest in performance technology".
But what is this wrist band, which has also been spotted adorning the wrists of top athletes including David Beckham?
Hellomagazine.com got the lowdown on the latest celebrity craze, which claims to help improve the balance, strength and flexibility of whoever wears it.
"These benefits are attributed to the holograms featured on the band which are embedded with frequencies to react positively with your body’s natural energy field, helping to increase performance," explain the experts.
"Almost everything has a frequency inherent to it. Some frequencies react positively with your body, while others can have a negative effect.
"Power Balance was originally designed to help athletes perform at their best, but its benefits have been documented by people of all walks of life."
Diversity star Ashley Banjo is another fan. “We're in rehearsals for our tour in December and working really hard," he says. "Our Power Balance bands are really cool and we love the different colours!"
