Whats cooler than being cool? Ice Cold!
You might have noticed that a string of artists including Chris Brown and Iggy Azalea have been posting videos of themselves having buckets of ice water thrown over their head.
It's known as the 'ALS Ice Bucket Challenge', and it's spreading across social media like wildfire all to raise awareness and money for amyotrophic lateral sclerosis.
So far Chris Brown has taken part, challenging a host of his fellow artist friends, and Drake even did it on stage at the end of his collaborative tour with Lil Wayne.
