Most of Hollywood has been taking turns nominating each other for the ALS Ice Bucket Challenge, and they’re all being awesome about it! For example, Taylor Swift and Jaime King both got together with a group of people and lots of buckets of ice water and they donated $100 for each person who was there with them. Ryan Seacrest was pretty normal with his video in comparison to who nominated him Bill Gates, who had a pretty elaborate video. Also doing the Ice Bucket Challenge videos: Justin Bieber, Robert Downey Jr, Gwen Stefani, Tori Spelling, Steven Spielberg, Justin Timberlake, Vanilla Ice, Lance Bass, Carrie Underwood, and many more! Chris Pratt, star of Guardians of the Galaxy and Parks and Recreation, may have the best ALS Ice Bucket Challenge video! He decides to do things a little differently, and the outcome is pretty hilarious! If you haven't seen Cindy's Ice Bucket Challenge, check it out here!
