Justin and Selena do the Ice Bucket Challenge!

Selena Gomez and Justin Bieber have become the latest celebrities to do the Ice Bucket Challenge – a social media phenomenon where people get nominated to dump a bucket of icy water over their heads to raise awareness of Amyotrophic lateral sclerosis (ALS).

How exactly does this raise awareness for ALS? Who knows. It does seem to be working though as over $4 million has been raise for the charities involved. I'm sure this is why all the celebrities are doing it, and not so they can have wet t-shirts on camera.

Selena was nominated by Ryan Seacrest and Taylor Swift to get drenched, and she gamely took up the challenge, sharing the result on Instagram.

Selena posted another video afterward nominating Cara Delevingne, Suki Waterhouse and James Franco to take part in the challenge.

A few hours later, clearly social media stalking his on-again-off-again girlfriend, Justin Bieber posted his video. We can't help but feel he didn't put as much effort in however. Is that water even cold?

 

Bieber decided his nomination should go to… President Barack Obama. Yeah, I'm sure he'll get right on that.
