Carrie Underwood, Chris Pratt, Selena Gomez & Justin Bieber ALS Ice Bucket Challenge: Watch Hilarious Viral Videos From Superstars

Carrie Underwood, Chris Pratt, Selena Gomez, and Justin Bieber are just a few of the latest celebrities to participate in the ALS Ice Bucket Challenge. As more celebrities participate in the challenge to raise money and spread awareness for ALS (also known as Lou Gehrig's Disease) they in turn challenge more of their famous friends, and we get to watch all the hilarious videos.

Selena Gomez was challenged by her on-again, off-again bestie Taylor Swift along with Ryan Seacrest, to dump the freezing cold bucket of water on her head. In turn she nominated Cara Delevingne, James Franco, and Suki Waterhouse.

"Accepted!!! @ryanseacrest @Taylorswift my whole team is donating!," the starlet wrote on her Instagram page.

Meanwhile, Carrie Underwood and husband Mike Fisher took the challenge up a notch as they filled the troth of a backhoe up with ice water, which they then had their friend raise and dump over their heads.

After being drenched in freezing cold water, they passed the torch on to Jennifer Nettles, Shea Weber, and Trevor McNeven.

Justin Bieber also took to his Instagram account to participate in the challenge choosing instead to use a saucepan rather than a bucket, and calling out President Obama, Ellen DeGeneres, and Chris D'Elias to step up to the plate.

Guardian of The Galaxy star Chris Pratt however, just might be our favorite ALS video yet, as instead of dumping ice water on himself he chooses instead to get iced by drinking a Smirnoff Ice as well as a shot of Blue Ice vodka. He nominated three of his costars, from Gregory Smith from Everwood, from Parks and Rec Nick Offerman, and David Bautista from GOTG.
