Who would have thought this Iced Bucket Challenge for ALS would grow to be so massive that even celebs are joining in?  The latest pair to join the rankings of celeb icers are Jennifer Lopez and Justin Bieber.

J.Lo looked so hot in her work-out outfit, we would have guessed the ice would turn to steam once making contact with her skin.  Not quite the case but still a nice visual to leave you with.

As for the Biebs, a shirtless Justin iced himself and challenged all the “Beliebers” out there to take the challenge as well.

For those who don’t know, the #IceBucketChallenge was created to raise awareness and funds for Amyotrophic lateral sclerosis (ALS), often referred to as “Lou Gehrig’s Disease.” Hopefully these celebs are not only partaking in the ice portion but also writing some checks.

So, now you’ve seen J.Lo and you’ve watched the Biebs, who do YOU think iced better?
