Listen to One Direction on iHeartRadio

Harry Styles and Liam Payne have completed their Ice Bucket Challenges, and have nominated several others to take it on! Harry wrote:

"Wake up call. I nominate Irving Azoff, Kanye West and Susan Sarandon.... And Ben Winston. Donate too. Go?"

Will Kanye actually accept the challenge?! He has 24 hours...

Meanwhile Liam, who was nominated by Cheryl Cole, nominated Pharrell Williams, Sofia Smith, John C. Reilly, and Will Ferrell. 

The boys will be taking the stage with their fellow One Direction bandmates at next month's iHeartRadio Music Festival in Las Vegas.
