The campaign - intended to raise awareness of Amyotrophic Lateral Sclerosis, better known as Motor Neurone Disease in the UK - sees people dousing themselves in freezing water and then sharing the results on social media, but not before nominating three friends to do the same.
So far massive stars such as Oprah Winfrey, Bill Gates and Mark Zuckerberg have all got involved with the Ice Bucket Challenge, and now comedian and actor Russell Brand has got in on the act.
After being nominated by TV chef Jamie Oliver, Russell uploaded a video to his YouTube page on Thursday, having not one but two buckets of icy water thrown over him by “NHS employees”, with the comedian joking: “That way I’m protected.”
Russell was predictably creative with his nominations beforehand, choosing Prime Minister David Cameron, as well as media personalities Sean Hannity and Jeremy Paxman, both of whom he’s been engaged in pretty heated debates with in past interviews.
Let’s see if any of them rise to the challenge.
One star you definitely won’t be seeing involved in the ALS Ice Bucket Challenge any time soon is former ‘Baywatch’ actress Pamela Anderson, who publicly slated the campaign on her Facebook page, claiming that the ALS Association’s use of animal testing conflicts with her strong views in favour of animal rights.
