WATCH: OUR FAVOURITE SEXIEST CELEB ICE BUCKET CHALLENGES

We’re amazed by the astonishing wildfire-like spread of the ice bucket challenge phenomenon across social media.

The campaign has raised more than $31.5 million for the ALS (Amyotrophic lateral sclerosis) Association, which fights against what’s commonly known as Lou Gehrig’s Disease.

It sees people, including just about every celebrity known to man, videoing themselves being dunked with a bucket of ice water. They also challenge others to do the same.

The aim is to grow awareness of ALS, which it’s certainly achieved. The campaign has exploded across the world and it’s now also kicking off in South Africa.

In addition to it all being for a good cause, it’s also a great excuse to check out some hot celeb bods.

Here are some of our favourite (and hottest) ice bucket challenges – so far.
