Unfortunately, a bow and arrow won't protect Liam Hemsworth from bucket of ice cold water.

The Hunger Games hottie can now add himself to the long list of celebs who have accepted and successfully completed the ALS Ice Bucket Challenge, in order to promote awareness and raise money for amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease.

After being nominated by pal Ashley Greene, the actor's older brother Luke Hemsworth uploaded two videos of the 24-year-old star being doused in freezing cold water...while sporting a Teenage Mutant Ninja Turtle costume (natch).

"Thanks, Ashley, for nominating me for the Ice Bucket Challenge," he says before a tub of freezing cold water is tossed over his head without a moment's notice.

"I'm supposed to nominate people first!" the handsome thesp exclaims as he shakes out his hair. "I nominate Woody Harrelson, Josh Hutcherson and Matt Niven."

While Zoe Saldana opted out of the challenge due to her baby-on-the-way, fellow mama-to-be Hayden Panettiere was more than game to participate—and even choose to adorably nominate her baby-to-be as well as her fiancé.

"I accept the ALS Challenge and I re-nominate Kasey Musgraves, you're not getting out of this, Wladimir Klitschko and my unborn child," the 24-year-old beauty says in the clip before pal Derek Hough douses her with a ice cold water, igniting a loud shriek from Hayden, who successfully contained her urge to swear.

Believe it or not, even Anna Wintour accepted the challenge after being nominated by daughter Bee Shaffer, proving the fashion icon is willing to drench her famous—and always perfectly styled—bob haircut in the name of charity.

Following in the footsteps of hubby Justin Timberlake, Jessica Biel also took part in the challenge although she opted to up the ante by including both her mom and grandma (she proceeded to nominate Seth Meyers, Betty White and Adam Sandler).

Additional celebs who have completed the challenge include Behati Prinsloo, Diane von Furstenberg and Stephen King, joining the likes of Justin Bieber, Selena Gomez, Lady Gaga, Ben Affleck, Emma Stone, Shakira, David Beckham and many more, who have all taken part in the viral Internet sensation (heck, even Pope Francis has been nominated!). 

In just three weeks, the ALS Association has received $31.5 million in donations. To compare, the charity received $1.9 million in financial contributions during the same time period last year.
