Justin Timberlake is the latest celebrity on the bucket list.
The pop star accepted the ALS Ice Bucket challenge, which he did along with his back-up band, The Tennessee Kids, who joined in on the action.
Justin was challenged to complete the task by Patrick Downes and Jessica Kensky, a married couple who were both injured in the 2013 Boston Marathon bombings. Justin was given 24 hours to pour the bucket of ice -cold water over his head, or donate at least $100 to the ALS Foundation, which raises awareness for Amyotrophic Lateral Sclerosis, otherwise known as Lou Gehrig's disease.
Justin said on his Facebook post, "We did both...and then we donated a bunch more. It's such a good cause."
But as anyone that has been following the #IceBucketChallenge knows, it was Justin's turn to nominate more people to take on the mission.
"I'm going to pass this on and challenge Jimmy Fallon, Steve Higgins and The Roots from 'Fallon Tonight,' " he said before later adding after he poured the ice-cold bucket over his head. "You have 24 hours to respond."
