Using their fame to help others, Harry Styles and Liam Payne were photographed for a new campaign for the youth cancer charity Trekstock on Monday (July 8).

The One Direction band members are promoting the fundraising platform Prizeo to aid children and young persons battling the disease.

On Monday Harry wrote on Twitter, “If you fancy it, you can come and hang out with Liam and I for @trekstock?”

As part of the fundraiser, one lucky Directioner will be flown to London to spend an evening out with the two hunks.
