1D hunk is one of the latest celebs to take on the charity challenge that's gone viral
The ALS ice bucket challenge has been taking the online world by storm recently, with celebrities taking turns to nominate one another, to raise money for charity - the latest star being the one and only Niall Horan, who was left breathless after throwing a bucket of freezing water over himself.
After being nominated by Pearl Jam's Eddie Vedder, Niall stood in a shower room, whilst somebody filmed him first of all, saying who he was nominating to do the stunt next - the chosen ones being Louis Tomlinson, Johyn Terry and Novak Djokovic.

The 1D hunk then quickly grabbed a huge bin filled with icey water, and without any hesitation, threw it over his head. Understandably though, Niall was left a little shellshocked over the whole thing, with him turning around, before then seeming quite pleased with himself, screaming to the camera - and, rightly so!

And not only has the Irish stud done all of this for charity, but we also got a glimpse of his amazing abs underneath that white vest of his. Winners all round!
