One Direction have pledged to donate around £200,000 from ticket sales to a good cause.
The boyband - which is made up of Harry Styles, Zayn Malik, Louis Tomlinson, Liam Payne and Niall Horan - recently announced the Where We Are Tour, which will commence next year.
The worldwide stadium shows include dates in Peru, Brazil, Ireland and England so far, with tickets for the UK leg going on sale tomorrow.
The good-natured guys have now revealed that 50p from each UK ticket sold will go towards helping the Stand Up To Cancer cause.
Tickets will go from £40 upwards and it's expected the band will end up donating around £200,000.
"We're so proud to be supporting Stand Up To Cancer while touring the UK and Ireland. Cancer affects nearly everyone at some point in their lives so we all need to do what we can to bring forward the day when all cancers are cured," Liam told British newspaper The Mirror.
"Stand Up To Cancer is all about bringing people together as a collective force and we hope our fans will get involved too.... We'd love for One Direction fans to tell us about their support by using the hashtag #1DStandUp."
The boys are immensely popular and it's believed tickets will sell out within minutes.
The director of Stand Up To Cancer, Claire Rowney, has commended One Direction for their generosity and says the charity is "over the moon".
The boys are currently busy with the European leg over their Take Me Home Tour, which moves to North America in June.
