One Direction And JLS Are Ultimate Boyband Prize
Bands team up to help raise money for charity with spectacular contest...
The two acts - who both came to fame via The X Factor - are part of an "Ultimate Boyband Experience" prize on Cancer Research UK's new digital fundraising platform PRIZEO.COM.
The winner of the contest will get the chance to take four friends to one of 1D's soundchecks, where they'll be rehearsing all their songs for that night's gig.
The contest promises: "There will be some special surprises too, and the boys can't wait to see you there!"
It continues: "Next, you'll be taken for lunch by JLS at one of their favourite restaurants, for some one-on-one time. You'll also get to choose your favourite JLS song for the boys to serenade you with. We suggest you film it!
"Finally, in the evening you'll be invited to London's O2 arena as VIPs, where you'll get to watch One Direction live in concert from your very own private box, with JLS for company! Get ready to party!!"
The contest costs £1 per entry, and contestants must be aged 16 or over.
