A-list celebrities like Chris Pratt, Lady Gaga are among many more who have taken on the Ice Bucket Challenge.
Gaga recently posted her video via Instagram, where she is dressed in a leather leotard and doesn't speak a word, though she nominated Adele, Michael Rapino, Vincent Herbert, and Arthur Fogel for the challenge, the New York Post reported.

"Guardians of the Galaxy" star Chris Pratt, who was challenged by Disney president Bob Iger, not only took down some icy shots in his video, but he got multiple buckets of water dumped on his head and challenged Gregory Smith, Nick Offerman and Dave Batista.
The Ice Bucket Challenge is an effort to raise awareness of amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease, where participants must dump a bucket of ice water over their heads, but if they can't brave the chill, the alternative is to donate 100 dollars to the ALS Association.
