The latest celeb to take on the ALS Ice Bucket Challenge? Justin Timberlake!

According to Idolator, Justin and the Tennessee Kids were nominated by Boston Marathon bombing survivors. In a video posted to the singer's YouTube page, he explains that he has accepted their challenge.

For those not familiar with the ALS Ice Bucket Challenge, Justin is referring to a means of spreading awareness for Amyotrophic lateral sclerosis (ALS), which is also known as Lou Gehrig's disease. According to Billboard, the rules of the challenge state that a participant must dump a bucket of ice on his head within 24 hours of being nominated or donate at least $100 to the ALS Foundation.

In the video, Justin rallied his friends before the entire group dumped buckets of ice water on their heads. Brrrr! The 'Not a Bad Thing' singer passed on the challenge to his good friend Jimmy Fallon, as well as Steve Higgins and the Roots over at 'The Tonight Show.'

Watch the video above to see Justin accept the ALS Ice Bucket Challenge.
